#Difference
`==` (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:
js
// `true` is converted to 1 and then compared to 1
true == 1; // true
true === 1; // falseThe following table demonstrates the result of these operators:
#Good practice
Always use
`===` to compare values.#See also
