WebAssembly is important for the following reasons:
- WebAssembly code runs at a speed that is pretty close to the native speed, which means that WebAssembly is fast.
- You can create WebAssembly code from many programming languages, which might include programming languages that you already know.
- Most modern web browsers natively support WebAssembly without the need for a plugin or any other software installation.
- WebAssembly code is much faster than JavaScript code.
