January 5, 2019Wordpress alternatives for javascript practice
Hey, Gatsby might be a good one to try out. It's got a bunch of plugins for functionality, as well as nice themes for different styles.
Note that it is a different way of doing things, being JAM stack. That is, you don't have a server and an admin, but get the data from any number of places (simplest being markdown files), and generate the static site from the posts.
The main Gatsby tutorial takes you through building a blog, so maybe check it out and see what you think - https://www.gatsbyjs.com/tutorial/
Another option that's more like WordPress in JavaScript is Ghost. It's a more traditional server rendered blogging engine. I'm not sure about it's plugins, but it looks like it does have themes and integrations so maybe that's enough.
Hope that helps!

Great idea! And good design too! Here are two unrequested suggestions:P
I would take extra care for the mobile layout if I were on your team. There were a few things that I noticed that really took me out of the experience. One example is the bottom nav bar on mobile.
From a UX perspective it would be great to allow a mobile experience that doesn't require unlocking. In order to gain access to the flashcards it seems a user would need to first complete all sections on a larger device, which to me is less than ideal. I tend to lean towards a more sandbox type of approach for my users instead of locking them into a path.
Overall it looks VERY pretty and seems to be a great idea!

September 10, 2015How fast is the online JavaScript compiler?
PlayCode's compiler is optimized for speed. Initial compilation takes 100-500ms depending on project size. Incremental builds (when you edit code) complete in 20-50ms. That's often faster than running a local Node.js bundler because everything runs in memory with no disk I/O.

Does the JavaScript compiler work offline?
PlayCode works offline once loaded. The compiler runs entirely in your browser using WebAssembly, so you can keep coding without an internet connection. Your code is saved locally and syncs when you're back online.

What is a JavaScript compiler?
A JavaScript compiler transforms your JavaScript code into optimized, executable code. Unlike traditional compilers that produce machine code, JS compilers like PlayCode bundle your code, resolve imports, and transpile modern syntax (ES2026, TypeScript, JSX) into browser-compatible JavaScript that runs instantly.

r/learnjavascript on Reddit: What is a good website to practice JavaScript?
December 26, 2023 -
I am looking for a website with lots of JavaScript exercises that I can practice the concepts that I am learning. I am not so much looking a site to teach me JavaScript as I have plenty of sources to learn already. I know that there are many different places like LeetCode or Codewars, but I am not sure how beginner friendly they are. I was using Edabit, and it was perfect for what I was looking for, but it is not free unfortunately, and my free trial has ended, and I am not in the position to pay for practicing JavaScript at the moment. Is there a free alternative for Edabit?
