Adds special characters to text to print in color in the console (combined with console.log()).

• Use template literals and special characters to add the appropriate color code to the string output.
• For background colors, add a special character that resets the background color at the end of the string.

const colorize = (...args) => ({
  black: `\x1b[30m${args.join(' ')}`,
  red: `\x1b[31m${args.join(' ')}`,
  green: `\x1b[32m${args.join(' ')}`,
  yellow: `\x1b[33m${args.join(' ')}`,

  cyan: `\x1b[36m${args.join(' ')}`,

  bgBlack: `\x1b[40m${args.join(' ')}\x1b[0m`,
  bgRed: `\x1b[41m${args.join(' ')}\x1b[0m`,

  bgWhite: `\x1b[47m${args.join(' ')}\x1b[0m`
});

console.log(colorize('foo').red); // 'foo' (red letters)
console.log(colorize('foo', 'bar').bgBlue); // 'foo bar' (blue background)
console.log(colorize(colorize('foo').yellow, colorize('foo').green).bgWhite);
// 'foo bar' (first word in yellow letters, second word in green letters, white background for both)
