Summary

Throughout this chapter, we practiced how to use async/await when fetching data from a server. We also covered how to catch errors by using the try/catch pattern followed by how to use async/await inside loops. Firstly, we learned what a promise is and how to use it with three methods, then(), finally(), and catch(). Also, we discovered how to use Axios to use these three methods. After that, in the exercise, we practiced how to fetch data from OpenWeather API using Axios with then(), finally(), and catch(). After that, we dived into async/await by discussing what the async and await keywords are for. And then we talked about how to use then(), error(), and finally() methods with async/await, followed by an example of a benefit of using async/await over Promise while handling errors. In addition, we discussed how to use async/await within loops and saw an example of when to use for…of and map(), and also why the forEach() method is not recommended.
