@h

The first two !! do a type conversion to binary. The third inverts the binary value. The combination lets you do a C-style conditional of "not that, whatever it is".

I wish I didn't know this, and I wish javascruff wasn't such a shitty language.

@artemesia this isnt part of the language. this is an engine optimisation

hazel

@artemesia before wasm engines had things like this to make javascript run faster by being able to make much more drastic optimisations

hazel

@artemesia you try it??? it does the same thing as one exclamation point as far as a dev is concerned?
