FWIW: I didn't produce the content presented here (the outline from Edmond Lau's book). I've just copy-pasted it from somewhere over the Internet, but I cannot remember what exactly the original source is. I was also not able to find the author's name, so I cannot give him/her the proper credits.

By listing the first six prime numbers: 2, 3, 5, 7, 11, and 13, we can see that the 6th prime is 13.

What is the 10 001st prime number?

const isPrime = num => {
  const sqrt = Math.sqrt(num)
  for (let i = 2; i <= sqrt; i++) {
    if (num % i === 0) {
 return false

Sass Dark/Light Theme Mixin

Sass Dark/Light Theme Mixin

This is a Sass mixin to handle a 3-way dark mode. It relies on a data-theme attribute on your <html> element with a value of light or dark. If data-theme is absent (i.e. it's neither light nor dark), the system's preferred mode is used.

body {
  // matches data-theme="light" or data-theme="auto" with system instructing light mode
  @include light {
    background: white;
    color: black;
