Astro, the framework I used to build this site, contains built-in support for Shiki, a syntax highlighter.

Here is a list of themes that work out-of-the-box!

I currently used the github-dark theme for all code blocks on this site.

// Example.ts
let num = [1, 2, 3]
num.forEach(function (value) {
  console.log(value)
})
