What statement do you flag as assumption? Yes, I do. The modulo operator is only a subset of bit masks. It is more explicit to write:
if ( (variable &EVEN_MASK) == 0) …
To act upon even numbers then:
if ( (variable %1) == 0) …
How would you name the 1 in the above statement for more expressive power?
EVEN_MODULO_OP ? That may throw more people off imo.

I give up, I was wrong to even think about the modulo operator, you are clearly the master programmer. 🥇
This reminds me of a discussion about the ternary operator
? :, some people think its the one true way of writing code because its just so clear what it does. And I say please use it sparingly because if you start doing nested ternary operators its very hard to unpack what your code does, and I prefer readability over compact code, especially with today’s compilers.uranibaba@lemmy.world 8 months ago
I feel you said about JavaScript as a whole.

Psh screw those people, they need to see my massive coder wang
if(!i&1){ … }
