# Value comparison operators
# Value Comparison Operators
In javascript, the `==` operator does the type conversion of the operands before comparison, whereas the === operator compares the values and the data types of the operands. The `Object.is()` method determines whether two values are the same value: `Object.is(value1, value2)`.
`Object.is()` is not equivalent to the `==` operator. The `==` operator applies various coercions to both sides (if they are not the same type) before testing for equality (resulting in such behavior as `"" == false` being `true`), but `Object.is()` doesn't coerce either value.
`Object.is()` is also not equivalent to the `===` operator. The only difference between `Object.is()` and `===` is in their treatment of signed zeros and `NaN` values. The `===` operator (and the `==` operator) treats the number values `-0` and `+0` as equal but treats `NaN` as not equal to each other.
