Getting started with AssemblyScript | WebAssembly | Tutorial

This video gives an introduction into AssemblyScript. AssemblyScript is a fun typescript based language that compiles down into WebAssembly. For folks who are experienced in JavaScript or Typescript and want to get started with WebAssembly this is the ideal language.

In this tutorial, I show you how to install AssemblyScript on your machine and get started with it in VSCode. We look at how easy it is to write some AssemblyScript including unit testing and running it in Node.JS. In addition we also look at how small and efficient the compiled WebAssembly is (and how close it is to code you would hand code yourself). Finally we look at the compiler optimizes the code you create. We look at the difference between optimized and optimized generated WebAssembly.

Chris,
That's an amazing introduction to as, to the point. Thank you!

I've been learning rust and wanted to give it a try to WASM. I must say your videos are really helpful and well explained. Thanks!!

Great video!
It would be amazing if you could show us (maybe you did in another video?) How to use this compiled module in the browser

Great video. Concise information. The right amount of technical info. What would be interesting would be a speed test AS vs TS, such as finding top 1000 prime numbers (or whatever speed test). One thing I would like to better understand is when WASM is the right choice vs JS given the pros\cons.

good videos & i like your presentation style also. I have watched this whole list and start follow you, on twitter. Please continue journey with 'C' and advance topics such as optimization

I want to see an array function done in AssemblyScript

I find it ironic that Rust is suitable for embedded programming but it produces a wasm file significantly larger than than this javascript-like language. Can you get a compact wasm file by writing Rust module like it is for an embedded application?

[ShaggtyDoo]

Is there a link to a repo? also. How do you overlay your code and videos? It looks cool.

[EladioRochaV]

Good video. Hope you keep uploading more WASM videos
I have a query, can people see the code found in wasm as it happens with javascript? Or in this case the code is obfuscated?

Running "npm run asbuild" returns the error "SyntaxError: missing ) after argument list". The solution is to install Nodejs version 16. On my system default install is Nodejs version 14.
