WASM Javascript Exercises

WASM & JS Talk and exercises

By Njuguna Mureithi @tweetofnjuguna

Introduction

Habari! I'm Njuguna Mureithi, a Senior Engineer from Nairobi, Kenya.

I started my coding journey in 2007 and sold my first software in 2010. I write code every possible day and have done so gaining more than a decade of real work experience. I enjoy learning new concepts and languages. I'm currently involved a lot with Rust and Javascript with a little bit of C.

Motivation

Why talk and sell WebAssembly?

• It is a W3C standard, supported by all major browsers
• It is faster than js (see Exercise 1)
• It is more secure than js
• It is universal (see Exercise 2)

Its also a chance to bring up a chance to talk about Rust :).

Insert funny tweet about someone @ me on this.

Why Rust?

• Safe concurrent programming - The ease with which this allows users to write efficient, thread-safe code.
• Static language, OG of WebAssembly
• Growing ecosystem, StackOverflow's most loved language for the 7th year!

Exercises

In a goal to make this session interactive, we are going to look at some exercises. These exercises will each tackle a specific concept:

• Exercise 1: Basics and how fast is WASM?
• Exercise 2: How would one run .wasm files in other platforms?
• Exercise 3: Can you build complex UIs in WASM?

Requirements:

• rust-lang https://www.rust-lang.org/tools/install
• wasm-pack https://rustwasm.github.io/wasm-pack/installer/

After installation, please refer to each exercise's Readme file for the next instructions.
