Join Eve Porcello for an in-depth discussion in this video Loading data with fetch, part of Learning ECMAScript 6.
- [Instructor] In the previous video,…we looked at how space people can help us…load data from an API.…Loading data is one of the things we have to do…quite a bit as developers, so there is a fetch function…that we can use to simplify all of this code.…Now the fetch function works natively in most browsers.…There are also node packages that work with fetch…like node fetch and isomorphic fetch.…So what I'm going to do here is I'm going to replace this code…using the fetch function.…
The fetch function is always going to take…in the URL for an API.…So here we'll use the same one.…You can copy and paste it if you choose.…I'll just type it here, api.open-notify.org/astros.json.…Fetch also has access to a then method,…which is going to execute as soon as the fetch has resolved.…So then is going to take in console.log.…Great.…So now I'm going to comment out our space people function,…and we'll take a look at what this returns.…
Fetch returns the entire response object.…And this object has inside of it,…if we check out the prototype, it has a json function…
