Understanding Data Types in JavaScript is very important because it determines what values you can assign.
JavaScript has dynamic data types that mean the same variable can be used to hold different data types
example
var a; // Datatype of a is undefined
a = 101; // Datatype of a is a Number
a = "Qandeel"; // Datatype of a is a String
You can try the JavaScript typeof
operator to check the data type of a variable
Example
console.log(typeof "text"); // text
console.log(typeof 5); // number
console.log(typeof ][); // object
