Strict Equality Operator (===)

In JavaScript, the strict equality operator === compares both the value and the type of two operands. This means that it will only return true if both the value and the type are identical.

"5" === "5"   // true

In this case, both the value and the type are the same, so the result is true.

"5" === 5   // false

Here, although the values might appear similar, the types are different (string and number), so the result is false. The strict equality operator does not perform type coercion; both the value and the type must be identical.
