— Hello
— Const isNaN = x => x !== x
— Brilliant way to check
— +1
— What does that do?
— Return true if x is NaN, false otherwise
— I am somewhat surprised I am not getting it haha
—
const x = NaNx === x // false
— This ONLY happens for NaN
— Oh I see, parenthesis are not required for single argument lambda
