How to simulate a NOR gate in JavaScript?

Question

Does anyone know a way to simulate a NOR-gate in JavaScript?

https://en.wikipedia.org/wiki/NOR_gate

From what I have seen so far the language has only AND and OR

Answer 1

You can use a reversed && like so:

var a = false;
var b = false;

if ( !a && !b ) {
    // some code
}
