Video Introduction Course Tutorial
This cheatsheet is designed to provide a quick reference guide for anyone getting started with WebAssembly. It covers the basic concepts, topics, and categories related to WebAssembly.
What is WebAssembly?
How does WebAssembly work?
WebAssembly code is compiled from other languages, such as C++, Rust, or Go, into a binary format that can be executed by the browser. The binary code is then loaded into the browser and executed in a sandboxed environment.
Why use WebAssembly?
WebAssembly offers several benefits over traditional web development approaches:
- Performance: WebAssembly code is compiled to run at near-native speeds, making it ideal for computationally intensive tasks.
- Portability: WebAssembly code can be written in a variety of languages, making it easier to reuse existing code and libraries.
- Security: WebAssembly code runs in a sandboxed environment, which helps prevent malicious code from accessing sensitive data or resources.
Getting Started with WebAssembly
To get started with WebAssembly, you will need to:
- Choose a language to write your code in. WebAssembly supports several languages, including C++, Rust, and Go.
- Install a compiler for your chosen language. There are several compilers available for WebAssembly, including Emscripten, Rust, and TinyGo.
- Write your code in your chosen language.
- Compile your code to WebAssembly using your chosen compiler.
A WebAssembly module is a self-contained unit of code that can be loaded and executed by a web browser. A module can contain one or more functions, as well as data and other resources.
WebAssembly provides a linear memory space that can be used to store data. Memory is allocated at runtime and can be accessed by WebAssembly functions.
WebAssembly tables are arrays of function references. They can be used to implement function pointers and other advanced features.
Imports and Exports
Compilers are tools that convert code written in one language into another language. In the context of WebAssembly, compilers are used to convert code written in languages such as C++, Rust, or Go into WebAssembly code.
Emscripten is a popular compiler for WebAssembly that can convert C and C++ code into WebAssembly code. It also provides a set of libraries and tools for working with WebAssembly.
Rust is a systems programming language that is designed for performance and safety. It has a built-in WebAssembly target, which makes it easy to write WebAssembly code in Rust.
Go is a programming language that is designed for simplicity and efficiency. It has experimental support for WebAssembly, which allows developers to write WebAssembly code in Go.
Debugging WebAssembly code can be challenging, as it is not directly readable by humans. However, there are several tools available for debugging WebAssembly code, including the browser's developer tools and specialized debuggers such as wabt.
WebAssembly is designed to be fast and efficient, but there are several factors that can affect its performance, including the size of the WebAssembly module, the complexity of the code, and the efficiency of the compiler.
WebAssembly is well-suited for gaming applications, as it can provide near-native performance for computationally intensive tasks such as physics simulations and AI.
WebAssembly can be used to create multimedia applications such as video and audio players, as well as image and video processing tools.
WebAssembly can be used for cryptography applications, such as encryption and decryption, as it provides a secure and efficient environment for these tasks.
WebAssembly can be used for machine learning applications, as it can provide near-native performance for tasks such as training and inference.
WebAssembly can be used for web development applications, such as web frameworks and serverless functions, as it provides a fast and efficient environment for running code on the web.
