Identity Operator

Definition:

An identity operator is a logical operator that compares two values and determines if they are identical, regardless of their data type.

Usage:

As a Comparison Operator:

The identity operator in programming languages such as JavaScript and Python is typically denoted as "===" or "is". It compares the values on both sides and returns true if they are identical, and false otherwise.

Example 1:

var x = 5;

var y = '5';

console.log(x === y); // Output: false

Example 2:

var a = [1, 2, 3];

var b = [1, 2, 3];

console.log(a === b); // Output: false

As an Identity Verification Tool:

The concept of identity operators is also used in authentication systems or identity verification tools, where it compares the provided information with the stored information to verify identity.

Example 3:

In a login system, a user's entered username and password can be compared with the stored username and password using identity operators to authenticate the user.
