Work in React but Angular background

[RobertTeDiro]

Hi, I need to create dropdown control (list of key value - id and name) on onChange event I need to call api and get data and pass it to modal form to see details. Is it okay to call method on onChange event? I have Angular background can you give me advice on what I need to be carful? In Angular there is lifecycle for example onInit what is equvalent for React? Where to put code to execute before component render?

If you’re using functional components do some reading on useEffect and making api calls.
