Someone told me that there's !< and !> in JavaScript. I tried it but it didn't work. Is there something like this in JavaScript? If not in JavaScript, is it there in any other language?

Short Answer: **NO**, you need to write it as `(!(something > something))` and vice-versa. – Mr. Alien Jul 08 '17 at 08:34

No. In JavaScript and many other languages (for numbers - not NaN - and strings):
"!<" is >=
"!>" is <=

Not all values are transitive to `>` and `<=`: `NaN > 5 // false`, `NaN <= 5 // false`. So technically `not >` is not `<=` in js typesystem. – zerkms Jul 08 '17 at 08:39

That's true. I edited my answer to clarify that is for numbers and strings only (which probable is his case) – Alberto Trindade Tavares Jul 08 '17 at 08:40

No !< and !> are not there in javascript and in most of the other programming languages too. You can try > instead of !< and < instead of !>
