JavaScript Cheat Sheet — JSON, Loops, and Promises

by dharmendra KUncategorizedLeave a Comment on JavaScript Cheat Sheet — JSON, Loops, and Promises

JavaScript is one of the most popular programming languages for web programming.

In this article, we’ll look at the basic syntax of modern JavaScript

JSON

We can create JSON strings from JavaScript objects with the JSON.stringify method:

And we can convert JSON strings back to JavaScript objects with JSON.parse :

const obj = JSON.parse(json);

We can use it to store data in local storage.

We’ve to convert objects into strings first to store them.

To store objects we call localStorage.setItem :

The first argument is the key.

And we can get data by their keys with getItem :

localStorage.getItem(‘json’)

Loops

avaScript comes with various kinds of loops.

One kind of loop is the for loop:

for (let i = 0; i < 10; i++) { console.log(i); }

We can loop through any kind of iterable object with the for-of loop:

for (let i of custOrder) { console.log(i); }

Some iterable objects include arrays, strings, and node lists.

Another kind of loop is the while loop:

There’s also the do-while loop:

The break keyword lets us end the loop early:

The continue keyword lets us skip to the next iteration:

Data Types

JavaScript comes with various data types.

They include:

Objects

We can create an object with curly braces:

It has properties and methods.

this is the student object itself.

We can call fullName with student.fullName() .

And we can assign values to properties with:

student.age = 19;

Promises

We can create promises with the Promise constructor:

We can resolve to fulfill the promise with the sum.

And we call reject to reject the promise with an error.

Then we can call then to get the resolved value and catch to get the error values:

Conclusion

We can work with JSON, local storage, promises, and loops with JavaScript.
