== vs ===

Written byPhuoc Nguyen

`==` (equality operator) and `===` (strict equality operator) are the operators to compare two operands.
The `==` operator does type conversions before comparing the values. On the other hand, the `===` operator doesn't perform any type conversions.
It means that the `===` operator returns `true` if two operands have the same type and same value.
For example:
// `true` is converted to 1 and then compared to 1
true == 1; // true
true === 1; // false
The following table demonstrates the result of these operators:

Good practice

Always use `===` to compare values.
