There is no need to explicitly cast the expression inside `if` statement to boolean, so we can remove `!!`.

Please let me know if it was done by intention @lukeed

Locally benchmarks show weird results even if I don't change anything

Hey, thank you

It was intentional. It's a deoptimization to have V8 infer/cast to boolean types for you. It may not greatly affect the benchmark numbers significantly (though usually it does), but at runtime/in the wild, it will leave the user code running in a deoptimized state

Good to know, thanks @lukeed
