Primitive data types in javascript

PRIMITIVE DATA TYPES IN JAVASCRIPT

JavaScript has seven primitive data types: String, Number, BigInt, Boolean, Undefined, Null, and Symbol.Primitive types are the most basic building blocks of data in JavaScript.

 They represent a single value and are immutable, meaning their internal values cannot be changed after creation.

The 7 Primitive Data Types

1. String :

Represents textual data. Strings must be enclosed in single quotes ('), double quotes ("), or backticks (`).

javascript

let name = "Alice";
let greeting = 'Hello';

2. Number :

Represents both integers and floating-point (decimal) numbers. It also includes special values like NaN (Not a Number) an Infinity.

javascript

let age = 25;
let weight = 50.1;

3. BigInt:

Large integers beyond the safe calculation limit of the standard Number type (ends with an n, e.g., 9007199254740991n).

4. Boolean:

logical entity with only two possible values: true or false.

javascript

let isCoding = true;
let isTired = false;


5.undefined

Automatically assigned to a variable that has been declared but not yet given a value.

let x console.log(x);

6. Null

Represents an intentional absence of any object value. It is used to explicitly state that a variable is empty.

javascript

let emptyValue = null;
