Colorize text in the Node.js terminal

You've probably seen colored text in the console before, and you might have wondered how to do it yourself. In most environments, there are special Unicode characters that you can use to print text in color in the console. This can be useful for adding emphasis to certain parts of your output, or for making your logs easier to read.
Here's a handy table of the most common colors and their corresponding Unicode characters:
| Color | Text | Background |
| --- | --- | --- |
| Black | \x1b[30m | \x1b[40m |

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`
});

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)

| Color | Text | Background |
| --- | --- | --- |
| Black | \x1b[30m | \x1b[40m |
| Red | \x1b[31m | \x1b[41m |
| Green | \x1b[32m | \x1b[42m |
| Yellow | \x1b[33m | \x1b[43m |
