Showing a refactor of a function with if statements to use key/value pairs in an object

if-to-object.js

/* Before */
function getErrorMessage(error) {
  if(error === 'username') {
    return `Username is required`
  } else if (error === 'email') {
    return `Don't forget your email!`
  } else if (error === 'password') {
    return `Please enter your password`
  }
}

/* After */
function getErrorMessage(error) {
  const errorResponses = {
    username: `Username is required`,
    email: `Don't forget your email!`,
    error: `Please enter your password`
  }

  return errorResponses[error]
}
