It is also necessary for Full Stack Developers to upgrade their JavaScript knowledge as and once new frameworks, libraries, and tools are launched. excluding this, Full Stack Developers should know how to use DOM and JSON.

Git and GitHub
As for Full Stack Developers, git permits them to trace each minor modification done to the application codebase. They need to remember all the essential git commands and examples. Using git empowers Full Stack Developers to explore distinctive opportunities for security, productivity, and management knowledge of git permits Full Stack Developers to higher collaborate and collaborate with their fellow developers/programmers who are working on a similar project.

Backend languages
While we’ve covered the two most important frontend languages, HTML and CSS (along with JavaScript), the other crucial part of an application or software is that the backend. whereas backend development could be a whole totally different game, there are lots of programming languages to settle on from. Doing a full-stack internet development course can assist you to learn the specified languages necessary to become a full-stack developer.

Web architecture
Full Stack Developers need to recognize the core of the net design. Since their primary responsibility is to develop advanced software system applications from scratch, they need to know how to structure the code, categorize the files, structure the information in databases, and perform the required process tasks.

HTTP and REST
Both HTTP and REST serve two unique functions. HTTP is that the protocol used for facilitating communication with the consumer, whereas REST is an interface between systems using the HTTP protocol to assemble information or perform completely different operations (in varied formats) on the info. So, REST acts as sort of a translator between the frontend and also the backend.

Database storage
All web applications need a database where all the data will be stored. This is to ensure that developers can access the data later. Database storage calls for an experienced and skilled Full Stack Developer who knows relational databases and database storage inside-out. Full-stack developers must be adept in database management – they should be able to design, understand, and manipulate database queries. They must also know how to work with XML and JSON.

Basic design skills
As we’ve made it clear that a Full Stack Developer is concerned with frontend and backend, they must possess fundamental design skills. The knowledge of frontend design is crucial to make a website look attractive and appealing. A website with a neat and user-friendly design always wins the hearts of the users.
Thus, Full Stack Developers must know the basic design principles, including UI & UX design, prototypes, scalability, etc.

NPM
NPM is the package manager explicitly designed for Node.js. It aids in the installation of different packages. It also offers relevant solutions for various dependencies. NPM allows developers to place modules optimally to help the node to find them and manage the dependency conflicts accordingly. NPM is highly configurable, and thus, it can be used for many applications, including the development, publishing, discovery, and installation of node programs.

Soft skills
When you aspire to become a Full Stack Developer, technical skills solely won’t suffice. You must possess the perfect balance of technical knowledge and soft skills. Every Full Stack Developer must have the following soft skills:
1. An analytical bent of mind
2. Good time management skills
3. Curiosity for learning
4. Attention to detail
6. Creative vision
7. Patience

Add each array element to the lines of a file in ruby

scmuser created the topic: Add each array element to the lines of a file in ruby

Add each array element to the lines of a file in ruby

Either use Array#each to iterate over your array and call IO#puts to write each element to the file (puts adds a record separator, typically a newline character):

File.open("test.txt", "w+") do |f|
a.each { |element| f.puts(element) }
end

Or pass the whole array to puts:

File.open("test.txt", "w+") do |f|
f.puts(a)
end

What is the way to iterate through an array in Ruby?

This will iterate through all the elements:

array = [1, 2, 3, 4, 5, 6]
array.each { |x| puts x }

Prints:
1
2
3
4
5
6

This will iterate through all the elements giving you the value and the index:

array = ["A", "B", "C"]
array.each_with_index {|val, index| puts "#{val} => #{index}" }

Prints:

A => 0
B => 1
C => 2
