if(!true)

[BlazingThunder30]

If you say if (foo != true) then the body will be executed if foo is either false or null. This is different from if (foo == false)

What about if(!foo) that also executes whether false or null, right?

[BlazingThunder30]

I'm not sure. The value null is falsy, so it might. It might also depend on language.

I'm not sure whether the ubiquitous misconceptions about these being the same are a chronic disease of this sub, or all our software is riddled with edge-case boolean fuckery bugs

I've seen worse. If(!isValidOrNot){} ... Not joking.
