In JavaScript =, == and === serve different purposes in the context of programming.
= (Assignment Operator) :
Used to assign a value to a variable.

let x = 3; //Assigns the value 3 to the variable x

== (Loose Equality):
Compares two values for equality, allowing type coercion.
Converts operands to the same type before comparison.

0 == '0'; // true (string is converted to a number)
null == undefined; //true

=== (Strict Equality):
Compares two values for equality without type coercion.
Both the type and value must be the same for the comparison to be true.

0 === '0'; // false (different types)
null === undefined; //false (different types)

Use = for assignments.
Use == for loose equality checks.
Use === for strict equality checks.
For reliable comparison, prefer ===.
