index.js

'use strict'

// All these functions behave the same way

const getHello = function (a) {
  if (a === true) {
    return 'hello' 
  }
  else { 
    return 'wow' 
  }
}

const getHello = function (a) {
  if (a === true) {
    return 'hello'
  }
  return 'wow'
}

const getHello = (a) => { // https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/Arrow_functions
  if (a === true) return 'hello'
  return 'wow'
}

const getHello = (a) => {
  if (a) return 'hello' // Checks for truthy values instead of true
  return 'wow'
}

const getHello = (a) => a ? 'hello' : 'wow' // https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Conditional_Operator
