Reading Notes for Day 28 of 401:
effects hook
- What purpose does useEffect serve in a function component compared to its counterpart(s) in class components? It lets you perform side effects in function components.
When using the useEffect Hook:
-
What does useEffect do? It allows you to run some additional code after React has updated the DOM.
-
Why is useEffect called inside a component? Runing it inside the component lets us access the count state variable (or any props) right from the effect.
-
Explain the importance of properly implementing effects with Cleanup If you don’t properly clean up after some effects, you can introduce bugs because of the behavior of the leftover code.
Reflection
- What are your learning goals after reading and reviewing the class README? My goal at this point is just to try to make my code work.
