randomHexColorCode

Generates a random hexadecimal color code.

Use Math.random to generate a random 24-bit(6x4bits) hexadecimal number. Use bit shifting and then convert it to an hexadecimal String using toString(16).

const randomHexColorCode = () => {
  let n = (((Math.random() * 0xfffff)) << 6).toString(16);
  return '#' + n.slice(0, 6);
};

randomHexColorCode(); // "#e34155"
