Using asynchronous web APIs from WebAssembly | Articles | web.dev

The I/O APIs on the web are asynchronous, but they're synchronous in most system languages. When compiling code to WebAssembly, you need to bridge one kind of APIs to another—and this bridge is Asyncify. In this post, you'll learn when and how to use Asyncify and how it works under the hood. I/O in system languages I'll start with a simple example in C. Say, you want to read the user's name from a
