Is it possible to create custom operators in JavaScript?

Question

During the Math classes we learned how to define new operators. For example:

(ℝ, ∘), x ∘ y = x + 2y

This defines ∘ law. For any r

Answer 1

No. You can't do that in JS.

The closest you can have IMO is to implement your own object which has a chainable interface, aka "fluent" syntax. That way you can operate as if you were speaking out in sequence.

var eq = new YourEquationObject();

// Then operate like 1 - 2 * 3
eq.add(1).sub(2).mul(3);

Details are up to you though. Just giving out an idea.
