Conditional Flow Control

conditionalFlowControl.js

/* Instead of using this:
const getNumWord = (num) => {
  if (num === 1) {
    return 'one';
  } else if (num === 2) {
    return 'two';
  } else if (num === 3) {
    return 'three';
  } else if (num === 4) {
    return 'four';
  } else return 'unknown';
};
console.log(getNumWord(1)); // one
console.log(getNumWord(3)); // three
console.log(getNumWord(7)); // unknown

Or even this:
const getNumWord = (num) => {
  switch (num) {
    case 1:
      return 'one';
    case 2:
      return 'two';
    case 3:
      return 'three';
    case 4:
      return 'four';
    default:
      return 'unknown';
  }
};
console.log(getNumWord(1)); // one
console.log(getNumWord(3)); // three
console.log(getNumWord(7)); // unknown

This is best:

const getNumWord = (num) =>
  num === 1
    ? 'one'
    : num === 2
    ? 'two'
    : num === 3
    ? 'three'
    : num === 4
    ? 'four'
    : 'unknown';
console.log(getNumWord(1)); // one
console.log(getNumWord(3)); // three
console.log(getNumWord(7)); // unknown
