What is === ? is it the same like ==?

Hi

I want to know what is different between == and === ? is === for objectives? Please show some examples.

The difference between === and == is that === checks for the value and type while == checks for the value only.

Example,

const a = 1;
const b = 1;

console.log(a === b); // true
console.log(a == b); // true

const c = 1;
const d = '1';

// Here you are checking for both the value, which both are equal to 1, 
// but you are also checking for the data type, which both have different data types.
// c is an integer while d is a string
console.log(c === d); // false 

// Here you are only checking for the value, which both are equal to 1
console.log(c == d); // true
