# jsIdentical function

1. @Since.new('3.12')

bool jsIdentical(

1. Object? a,
2. Object? b

)

Returns true if the underlying JavaScript values of `a` and `b` are identical.

The semantics are equivalent to the `===` operator in JavaScript. For backends that do not directly use JS values, the underlying JS value backing the native object will be compared using JS `===`. This should mean that the result of this should be consistent across backends unlike identical which only compares the native references.

`jsIdentical(a,b)` does not necessarily imply `a.runtimeType == b.runtimeType` or `a.hashCode == b.hashCode` as the JS values being compared may be wrapped by different native types. So a and b themselves cannot be used interchangeably.

## Implementation

    @Since('3.12')
    external bool jsIdentical(Object? a, Object? b);
