Fetch JavaScript
2 min readFeb 5, 2022
JavaScript can send network requests to the server and load new information whenever it’s needed.
For example, we can use a network request to:
- Submit an order,
- Load user information,
- Receive latest updates from the server,
- …etc.
The fetch() method is modern and versatile, so we’ll start with it. It’s not supported by old browsers (can be polyfilled), but very well supported among the modern ones.
