### colorize
Add 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.
```js
const colorize = (...args) => ({
black: `\x1b[30m${args.join(' ')}`,
red: `\x1b[31m${args.join(' ')}`,
green: `\x1b[32m${args.join(' ')}`,
yellow: `\x1b[33m${args.join(' ')}`,
blue: `\x1b[34m${args.join(' ')}`,
magenta: `\x1b[35m${args.join(' ')}`,
cyan: `\x1b[36m${args.join(' ')}`,
white: `\x1b[37m${args.join(' ')}`,
bgBlack: `\x1b[40m${args.join(' ')}\x1b[0m`,
bgRed: `\x1b[41m${args.join(' ')}\x1b[0m`,
bgGreen: `\x1b[42m${args.join(' ')}\x1b[0m`,
bgYellow: `\x1b[43m${args.join(' ')}\x1b[0m`,
bgBlue: `\x1b[44m${args.join(' ')}\x1b[0m`,
bgMagenta: `\x1b[45m${args.join(' ')}\x1b[0m`,
bgCyan: `\x1b[46m${args.join(' ')}\x1b[0m`,
bgWhite: `\x1b[47m${args.join(' ')}\x1b[0m`
});

```js
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)
