Asynchronous programming in JavaScript leverages features like callbacks, promises and async/await to sidestep this issue by allowing other code to run in the meantime.

Promises make asynchronous processing simple, consistent and easy to use. And, with TypeScript and Promises.TypeScript providing support for generic Promises, you get both type safety and IntelliSense ...

Promise-like features in various JavaScript libraries have emerged previously to give JavaScript applications support for asynchronous connections.

The WebAssembly JavaScript Promise Integration API suspends a Wasm application when it issues a synchronous API call and resumes it when the asynchronous I/O operation is completed.
