 hey guys how are you all today in this post I am going to give you the source code of my video called "types of datatypes of javascript" so let's begin:

here's the complete source code:-

// TYPES OF DATATYPES IN JAVASCRIPT

// Datatypes are the type of data in a programme

// Javascript has the following data types:

// * number

// * string

// * object

// * boolean

// * undefined

// NUMBER -> of two types

let num1 = 23; // this is a integer number -> number

let num2 = 23.43 // this is a float number -> number

// STRING -> can be written by two types

let str1 = "Like, Share and Subscribe"// this is a string written inside double quotes -> string

let str2 = 'Like, Share and Subscribe'// this is a string written inside single quotes -> string

// OBJECT -> is a key-value pair

let obj1 = {

    gautam: 99.9,

    pranav : 85

}

// BOOLEAN -> TRUE OR FALSE

let bool1 = true;

let bool2 = false;

console.log(obj1)

// UNDEFINED

let no;

console.log(typeof(num1));

console.log(typeof(str1));

console.log(typeof(obj1));

console.log(typeof(bool1));

console.log(typeof(no));
