randomHexColorCode

Generates a random hecadecimal color code.

Use Math.random to generate a random number and limit that number to fall in between 0 and 16 using Math.floor. Use the generated random number as index to access a character from 0 to F. Append it to color till the length is not 7.

const randomHexColorCode = () => {
  var color = '#';
  while(color.length < 7) color += '0123456789ABCDEF'[Math.floor(Math.random() * 16)];
  return color;
}

// randomHexColorCode() -> "#e34155"
