function text(a) {

function hello(a) {
    return 'Hello ' + a;

In this tutorial we're going to build a set of parser combinators.

What is a parser combinator?

We'll answer the above question in 2 steps.

1. What is a parser?
2. and, what is a parser combinator?

So first question: What is parser?

function isOk(input) {
  if (Array.isArray(input)) return input.length > 0;
  if (typeof input === 'object' && input) return Object.keys(input).length > 0;
  if (typeof input === 'number') return true;
  return Boolean(input);
}
