Launch HN: Scrimba (YC S20) – Interactive video for learning to code


Howdy all, I’m Per, co-founding father of Scrimba.

We’re constructing an interactive video layout for instructing and studying how to code. The most important income is that students can stay the video and edit the code every time they need.

We think this is well-known is on tale of over 70% of of us that are attempting to study to code nowadays train movies. But since movies aren’t interactive, students close up mirroring the instructors’ code line-by-line in their local code editors. That is time drinking, and it generally causes problems with local dev atmosphere setup.

Scrimba solves these problems because it enables students to stay the screencast and regulate the instructors’ code instantly inner the participant. So when a Scrimba pupil feels at a loss for phrases, she jumps into the screencast and plays round with the code (editing, working, debugging) till she’s made sense of it. As a shatter result, she learns sooner.

Technically, this is feasible on tale of we now have merged the IDE and the video participant into one instrument. To admire the abilities in-depth, please respect this forged:

The Scrimba layout also opens the design for different facets that can additional make stronger the studying ride, enjoy procuring inner movies, in-video hyperlinks, audiovisual code feedback from lecturers, far flung pair programming between students, and additional. The extra we work with the layout, the extra of these opportunities we respect. So we now have determined to train the layout as the backbone for a web-based coding college as we proceed to make stronger it.

After launching a bunch of shorter classes the leisure couple of years, we launched our first fats-diploma program this summer season. It's called “The Frontend Developer Profession Path” and it comprises 75 hours of state and 100s of interactive coding challenges. It prices $19 per thirty days and the lecturers are smartly-identified instructors enjoy Gary Simon, Cassidy Williams, and Kevin Powell. College students are also paired up in Survey Groups, in utter to create the fetch studying ride feel less lonely. To this point, over 3000 of us from 110 different worldwide locations have enrolled.

Here’s a hyperlink to the route:

Fun truth: Scrimba is built entirely in Imba, a programming language that our CTO has created. It’s a Ruby-impressed language that compiles to JavaScript, and it excels at creating excessive-performant web apps. The predominant model of Scrimba turned into as soon as created on tale of Sindre wanted a smarter technique to coach Imba.
