Complete guide of TypeScript certification courses, tutorials & training

Tutorials

TypeScript lets you write JavaScript the method you actually want to. TypeScript is a typed superset of JavaScript that amasses to plain JavaScript. A TypeScript is a pure object concerned with classes, interfaces, and statically typed like C# or Java. Mastering TypeScript can support programmers to write object-oriented programs and have them compiled to JavaScript, both on the client-side and server-side.

TypeScript is a typed superset of JavaScript that compiles to plain JavaScript. It is pure object-oriented with classes, interfaces, and statically typed programming languages like C# or Java. You will need a compiler to compile and generate the code in the file. Basically, TypeScript is the ES6 version of JavaScript with some additional features.

TypeScript used for:

TypeScript remains a superset of the JavaScript language that devises a single open-source compiler and is developed mostly using a single vendor Microsoft. The goalmouth of TypeScript is to help catch faults first through a type system and to variety JavaScript development more proficient.

Why do we need TypeScript?

TypeScript simplifies JavaScript code, making it easier to read and correct. TypeScript offers highly creative development tools for JavaScript IDEs and performs, like static checking. TypeScript creates code easier to read and comprehend. Using TypeScript, we can create a huge development over basic JavaScript.

What do I need to learn to use TypeScript?

TypeScript is basically a JS linter. Or, JS with certification that the compiler can understand. Therefore, indifference to other languages comparable to CoffeeScript which enhances syntactic sugar, or else PureScript which does not look similar to JavaScript at all, you do not need to learn a ration to start writing TypeScript code. Kinds in TS are optional, and all JS file is an effective TypeScript file. But the compiler will protest if you have type mistakes in your first files, it does stretch you back to a JavaScript file that works as it did before. Anywhere you are, TypeScript will meet you there, and then it is informal to build up your skills progressively.

How to get started with TypeScript?

To compile your TS code, you need to install tsc short for the TypeScript compiler. The easiest way to do it is over the terminal. This can remain done simply through npm by using the following command:

If you want to use TypeScript with Visual Studio Code, there is a handy guide on their website.

Once you have installed tsc, you can compile your files with tsc filename.ts.

Migrating your files from JavaScript to TypeScript

Let’s say that we want to change the following JavaScript file to TypeScript due to odd behavior:

Good news. Any JS file is technically a valid TypeScript file, so you’re up to a great start – just switch the file extension to .ts from .js.

TypeScript has type inference, which means that it can automatically infer some of the types you use without you adding them. In this case, it presumes that the function sums two variables of type any, which is true but of no great use right now.

If we want to sum only numbers, we can add a type signature to my_sum to make it accept only numbers.

Now, TypeScript provides us with an error.

Good thing we found where the error is: To additional escape errors like these, you can also add kind definitions to variables.

TypeScript is quite flexible in what it can do and how it can help you.

Features of TypeScript:

To sum it up, I think TypeScript will remain to rise in popularity aimed at the predictable future. It offers great development knowledge, does not have much competition, and enjoys high acceptance rates among new open-source projects.

Object-Oriented Language: TypeScript offers a whole feature of an object-oriented programming language such as inheritance, classes, interfaces, modules, etc. In TypeScript, we can write code for both server-side as well as client-side development.

TypeScript supports JavaScript libraries: TypeScript supports all JavaScript elements. It permits the developers to use existing JavaScript code with TypeScript. Here, we can use each of the JavaScript frameworks, tools, and other libraries easily.

JavaScript is TypeScript: It means the code written in JavaScript with valid .js extension can be transformed to TypeScript through changing the extension from (.js to .ts) and compiled with other TypeScript files.

TypeScript is portable: TypeScript is portable because it can be executed on any device, browser, or operating system. It can be run in any environment where JavaScript runs on. It is not specific to any virtual machine for execution.

DOM Manipulation: TypeScript can be used to manipulate the DOM for removing or adding elements related to JavaScript.

TypeScript is just JS: TypeScript code is not executed on any browsers straight. The program written in TypeScript constantly starts with JavaScript then ends with JavaScript. Henceforth, we only need to know JavaScript to use it in TypeScript. The code written in TypeScript is compiled and transformed into its JavaScript comparable for the execution. This procedure is recognized as Trans-piled. With the support of JavaScript code, browsers can read the TypeScript code and show the output.

Advantage of TypeScript over JavaScript:

  • TypeScript continuously highlights errors at compilation time throughout the time of development, while JavaScript points out errors at the runtime.
  • TypeScript supports strongly typed or static typing, but this is not in JavaScript.
  • TypeScript runs on some browser or JavaScript engine.
  • Great tooling supports with IntelliSense, which offers active hints as the code is added.
  • It has a namespace concept through defining a module.

TypeScript Variables:

A variable is the storage location, which remains used to store worth info to be referenced and used by programs. It acts as a container for worth in code and must be professed earlier the use. We can declare a variable by using the var keyword. In TypeScript, the variable follows the same identification rule as of JavaScript variable declaration. These rules are –

  • The variable name must be an alphabet or numeric digit.
  • The variable name cannot start with digits.
  • The variable name cannot contain spaces and special personalities, but the underscore (_) and the dollar ($) sign.

In ES6, we can describe variables using the let and const keywords. These variables have similar syntax for variable declaration and initialization but differ in scope and usage. In TypeScript, there is continuously suggested to define a variable using the let keyword because it delivers the type protection.

The let keyword is similar to the var keyword in some respects, and const is a let that prevents re-assignment to a variable.

Collections in TypeScript:

TypeScript supports two kinds of collections:

arrays (where all the members are of the same type and are accessed by position)

tuples (where each member can be of a different type).

Control Statements in TypeScript:

1. If the statement

2. If else statement

3. If else if statement

If Statement

If the statement is used to execute a block of statements if the specified condition is true.

Syntax:

If else statement

If else statement is used to execute whichever of two blocks of statements depends upon the situation. If the situation is true and if the block will execute or else the block will execute.

Syntax:

If else if statement

If else statement is used to execute one block of statements from many depends upon the condition. If condition1 is true then the block of statements1 will be executed, else if condition2 is a true block of statements2 is executed, and so on. If no condition is true, and else block of statements will remain executed.

Syntax:

TypeScript Control Statements Example:

What is a TypeScript application?

Software, web development, programming concept. Abstract Programming language and program code on screen laptop. Laptop and icons company network. Technology process of Software development (Software, web development, programming concept. Abstract Pr

TypeScript is a programming language developed then maintained through Microsoft. It is a strict syntactical superset of JavaScript and adds elective static typing to the language. TypeScript might be used to develop JavaScript applications for both server-side and client-side execution as with Node. Js or Deno.

Scope of TypeScript:

Variable scopes in TypeScript: Here scope means the discernibility of variable. The scope describes that we can access the variable or not. TypeScript variables can be of the following scopes:

Local Scope: As the name stated, are professed within the block like methods, loops, etc. Local variables are available only within the construct where they are declared.

Global Scope: If the variable is professed outside the construct then we can access the variable anyplace. This is recognized as Global Scope.

Class Scope: If a variable is professed inside the class and we can access that variable within the class only.

What are the Objectives for TypeScript Training?

•             Comprehend TypeScript conceptions

•             Apply different techniques to visualize data using multiple graphs and dashboards

•             Tool TypeScript in the organization to monitor operative intelligence

•             Troubleshoot various application log issues using SPL (Search Processing Language)

•             Implement indexers, forwarders, deployment servers, and deployers in TypeScript.

What are the benefits of TypeScript Certification?

Certifications continuously play a critical role in any occupation. You might find some Pay-Per-Click Intermediate specialists who will tell you that certifications do not hold considerable value; this certification validates an individual’s capability to generate complex searches, reports, and dashboards with Pay-Per-Click Intermediate’s core software to become the most out of their data. A Pay-Per-Click Intermediate Core Certified Operator can search, use fields, use lookups, and make basic statistical bits of intelligence then dashboards in the Pay-Per-Click Intermediate Initiative or Pay-Per-Click Intermediate Cloud Platforms. This certification validates an individual’s capability to navigate then use the Pay-Per-Click Intermediate Software.

Conclusions

Overall, TypeScript is a great tool to have in your toolset even if you do not use it to its full capability. It is informal to start small and grow slowly, learning and adding new features as you go. TypeScript is practical and welcoming to beginners, so there is no need to be afraid.

Tutorials for PHP Operators

What is Operators in PHP?

Operators are symbols that tell the PHP processor what actions should be taken. The Add (+) sign, for example, instructs PHP to combine two variables or values, but the bigger (>) symbol instructs PHP to compare two values. Don’t make the mistake of assuming that operators and functions are the same. Instead of functional, such operators might be used (such as the PHP ternary).

  • Arithmetic operators
  • Assignment operators
  • Comparison operators
  • Increment/Decrement operators
  • Logical operators
  • String operators
  • Array operators
  • Spaceship operators

Tutorials for PHP Data type

What is Data Types?

Their sizes, as well as the names of the variables, might change. In most programming languages (such as C++ and Java), you may use a number of data types for variables. However, because PHP does not specify type explicitly, the variable type must be determined by the form or type of data to which it is applied.

What are the Data Types used in PHP?

PHP Data Types - Tutorial And Example

There are many data types for various purposes, such as null, binary, integer, float, text, object, property, and an array. We employ eight different types of data in PHP to create our variables. Below is a brief explanation of the various categories.

Basic of PHP

Integers − There are whole numbers, including 4195, without a decimal point.

Doubles − Floating points are numbers such as 3.14159 or 49.1

Booleans − Have either true or false only two possible values.

NULL − It has only one value: NULL, is a special kind.

Strings − There are character strings, such as ‘PHP supports string operations.’

Arrays − Collections of other values are called and indexed.

Objects − There are instances of programming classes that can package other class-specific values and functions.

Resources − Special variables provide access to external PHP tools (such as database connections).

Configure the Knife Command – Chef

configure-the-knife-command

We now have to configure the knife command. This command is the central way of communicating with our server and the nodes that we will be configuring. We need to tell it how to authenticate and then generate a user to access the Chef server.

Luckily, we’ve been laying the groundwork for this step by acquiring the appropriate credential files. We can start the configuration by typing:

knife configure --initial 

This will ask you a series of questions. We will go through them one by one:

WARNING: No knife configuration file found Where should I put the config file? [/home/your_user/.chef/knife.rb]

The values in the brackets ([]) are the default values that knife will use if we do not select a value.

We want to place our knife configuration file in the hidden directory we have been using:

/home/your_user/chef-repo/.chef/knife.rb

In the next question, type in the domain name or IP address you use to access the Chef server. This should begin with https:// and end with :443:

https://server_domain_or_IP:443

You will be asked for a name for the new user you will be creating. Choose something descriptive:

Please enter a name for the new user: [root] station1

It will then ask you for the admin name. This you can just press enter on to accept the default value (we didn’t change the admin name).

It will then ask you for the location of the existing administrators key. This should be:

/home/your_user/chef-repo/.chef/admin.pem

It will ask a similar set of questions about the validator. We haven’t changed the validator’s name either, so we can keep that as chef-validator. Press enter to accept this value.

It will then ask you for the location of the validation key. It should be something like this:

/home/your_user/chef-repo/.chef/chef-validator.pem

Next, it will ask for the path to the repository. This is the chef-repo folder we have been operating in:

/home/your_user/chef-repo

Finally, it will ask you to select a password for your new user. Select anything you would like.

This should complete our knife configuration. If we look in our chef-repo/.chef directory, we should see a knife configuration file and the credentials of our new user:

ls ~/chef-repo/.chef 
admin.pem  chef-validator.pem  knife.rb  station1.pem
