I want to know for react class component we have componentWillMount() lifecycle method, where we can perform tasks before loading the component. Tasks like, a call to backend and use the response to show that data in that frontend. What if I want the same thing in a functional component? like I have used react chartJS and for that the data values I want to be retrieved from backend response, and then the chart will populate based on those datas.
I hope I explained the problem statement well, if not please ask for any information.
