Special terms are normally found in documentation and technical articles. But some of them like closures are pretty standard things to know about. Knowing what the word itself means can help you know the concept it's named for better.

Idiomatic Data Fetching using React Hooks

This post has been written in collaboration with @klervicn

Virtually all web apps and websites need to pull data from a server, usually through a JSON-returning API. When it comes to integrating data fetching in React component, the "impedence mismatch" between the React components, which are declarative and synchronous, and the HTTP requests, which are imperative and asynchronous, is often problematic.

Many apps use third-party libraries such as Redux or Apollo Client to abstract it away. This requires extra dependencies, and couple your app with a specific library to perform data fetching. In most cases, what we want is a direct way to integrate plain HTTP requests (e.g. using native fetch) for usage in React components.

Here we will discuss how we can use React Hooks to do this in an elegant, scalable manner.
