Generating Random Hex Color in JavaScript

Problem: I needed a quick way to generate random hex color codes for dynamic styling in JavaScript

Solution: I wrote a simple function that generates a random hexadecimal color by using Math.random() and converting it to a valid hex color string

function getRandomHexColor() {
  return `#${Math.floor(Math.random() * 0xffffff).toString(16)}`;
}

Keywords: JavaScript random color, generate hex color, dynamic hex color generation, random color generator, random styling in JavaScript, hex color string.
