Expert-Level Explanation

In JavaScript, == (equality operator compares two values for equality after performing type coercion if the types are different. === (strict equality operator) compares both the value and the type without type coercion.

Creative Explanation

==is like saying two people are similar because they both have hats, ignoring other differences. === is like saying they're the same only if they have hats of the same colour and style.

Practical Explanation with Code

console.log('2' == 2); // true, type coercion happens
console.log('2' === 2); // false, different types

Real-world Example

==is like matching socks by colour regardless of size, while === matches socks by both colour and size.
