How to use Logical Nor in JavaScript

To start coding in JavaScript, access the Terminal/SSH and type node. Logical Nor checks if none of the given arguments are true. To return the inverse of the logical or of two values, use the logical not (!) operator. Here's an example:

const nor = (a, b) => !(a || b);

And here are some outputs:

nor(true, true); // false
nor(true, false); // false
nor(false, false); // true
