JS Pop Quiz: How well do you know your functions?

foreach-fn-call.js

// the array of functions
const fns = [
  function () {
    console.log(1)
  },
  function () {
    console.log(2)
  },
  function () {
    console.log(3)
  }
]

// https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/Method_definitions
const call = {key(func) {func()}}.key

fns.forEach(call) // change this line if you like

// Expected console output should be
// 1
// 2
// 3

ahhh, yeah I didn't disallow method definitions explicitly, but I wouldn't consider this a valid solution as it's basically creating an anonymous function without creating an anonymous function. The intended point of this quiz is to get people thinking about how to invoke a function without creating a new wrapper function.

It does mention "do not create named functions". Updated gist to explicitly disallow method definitions.

Though you're the first one to use this trick so you get some points for creativity 👍
