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 = () => '#' + (Math.random() * 0xFFFFFF << 0).toString(16);

randomHexColorCode() // "#e34155"
randomHexColorCode() // "#fd73a6"
randomHexColorCode() // "#4144c6"
