// I have some testing framework in the scope
// Questions below:

// 1. Should the description be like it is here, in first `it`, or with `only` word added:
//    "should return Fizz when the number is divisible only by 3"
//    That would imply that the number is divisible by 3 only, which is technically not true, as it is divisible
//    by 1 as well, and some numbers, e.g. 6, 9, and so on, are divisible by themselves.
it('should return Fizz when the number is divisible by 3', () => {
    // 2. Is that name enough, having `any` in it, to be complete in what numbers are producing `fizz`.
    //    There is also a matter of adding `only` (similar to case #1) having `anyNumberDivisibleOnlyBy3`.

JSSR - JavaScript Standards Recommendation

Mind: this is a draft

Why?

I have found PHP's PSRs to be a very good idea when it comes to having some sorts of standards for commonly performed tasks. Wheter it's logging, caching or performing HTTP calls.

What are PSRs? Here's a short description taken from Wikipedia:

describe('executing handlers', () => {
    context('for synchronous handlers', () => {
        it('should happen in sequence', async () => {
            const hook1 = {
                event: 'preEventName',
                handler: sinon.spy()
            };
            const hook2 = {
                event: 'preEventName',
                handler: sinon.spy()
