Is there !< and !> in JavaScript?

Question

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

No. In JavaScript and many other languages (for numbers - not NaN - and strings):

"!<" is >=

"!>" is <=

Check this: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Comparison_Operators

Not all values are transitive to > and <=: NaN > 5 // false, NaN <= 5 // false. So technically not > is not <= in js typesystem.

That's true. I edited my answer to clarify that is for numbers and strings only (which probable is his case)

NaN is a number.

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