 Let's do a brief introduction into major concepts of WebAssembly:
 
 - WebAssembly is a compile-targeted language for running bytecode on the web.
-- Relative to Javascript, WebAssembly offers predictable performance. It is not inherently **faster** than Javascript, but it **can be faster than JavaScript** in the correct use case. Such as **computationally intensive tasks**, like nested loops or handling large amounts of data. Therefore, **WebAssembly is a compliment to JavaScript, and not a replacement**.

 - WebAssembly is extremely portable. WebAssembly runs on: all major web browsers, V8 runtimes like [Node.js](https://nodejs.org/en/), and independent Wasm runtimes like [Wasmtime](https://wasmtime.dev/), [Lucet](https://github.com/bytecodealliance/lucet), and [Wasmer](https://github.com/wasmerio/wasmer).
 - WebAssembly has Linear Memory, in other words, one big expandable array. And in the context of Javascript, synchronously accessible by Javascript and Wasm.
 - WebAssembly can export functions and constants, And in the context of Javascript, synchronously accessible by Javascript and Wasm.
