console.warn('It is a good idea to use .map instead of a for-loop.')
// Same as console.log(), but prints in red as an error. Useful to show a breaking error in a dev env.
console.error(`The value must be an integer. You provided a ${typeof variable}.`)
// Group console data together for better viewing. Nice to group console logs together.
