Variables and Data Types in Java Script

  Variables and Data Types in Java Script

In JavaScript, variables are used to store data values. There are three keywords used to declare variables in JavaScript: var, let, and const.

Here's an example of how to declare a variable using the var keyword:

javascript

var x = 5;

This creates a variable named x and assigns it the value of 5.

Data types in JavaScript include strings, numbers, booleans, null, undefined, and objects. Here's an example of how to declare a string variable:

javascript

var myName = "John";
