Version

Reproduction link

Steps to reproduce

Run tests across some modern browsers to see the result.

What is expected?

Custom bind implementation performance is the same level as native.

What is actually happening?

Custom bind implementation performance is lower than native.


Tested in:

  • Safari - native is slower 83%
  • Chrome - native is faster 61%
  • Edge - native is faster 91%
  • Firefox - native is faster 52%

I believe it is not an issue at all, but I think it is something which can be improved.
