What is the difference between `==` and `===` in JavaScript?

Answer

Previous Question Next Question

In JavaScript, "==" is used for loose equality comparison, which means it checks for equality of values after type conversion, while "===" is used for strict equality comparison, which checks for equality of both value and type without converting types.

// Loose equality
        console.log(5 == '5'); // true, because '5' is converted to a number

        // Strict equality
        console.log(5 === '5'); // false, because the types are different (number vs string)

Additional Comment:

Use "==" when you want to compare values with type conversion.
Use "===" when you want to ensure both value and type are the same.
Prefer "===" for most cases to avoid unexpected results due to type coercion.
