How I made savvas.me

A thread 🧵👇 Image
1⃣ The stack:

I wanted my website to be as fast and snappy as possible.

Which is why this website is 100% Jamstack. The code, posts, assets are all stored in a repository on Github - github.com/savvasStephani….

...and the website itself is made with Gatsby. Image
2⃣ Hosting

For my website, I wanted for the builds to execute immediately after pushing new changes.

The Markdown blog files, the assets (images, videos), JS files, styling etc are all hosted on Github.

The end result from building the website is hosted and managed on Netlify. Image

If you're learning Javascript, sooner or later you'll come across the forEach() and map() functions. It is quite often that there is some confusion about what each one does.
