In JavaScript, which is overall more efficient? Using IFs statements, Swith-Case, or K-V pair object with anonymous function? I have seen people using IFs- S-C and my self using K-V objects(something I picked from C# unfortunately).

Unreadable code

Same here. Never seen one like this before and I am new to JS to begin with

nothing wrong with a classic

YandreDev'd

Almost the same

I have the same thing. I am getting it as input. Shouldn't they be squared in the second list?
[42, 42]
[42, 42]

As well as the second guy who has an empty list which should return false, not true.
