QUESTION
I am a beginner at React.js. Trying to optimize my code (a simple Calculator on reactjs). I have many subfunctions for handle some operations like add new Number, or choose Operation (+, -) and etc. How to refactor them, to make only one function to handle all operations in one place?
code from App.js
...ANSWER
Answered 2020-Sep-27 at 16:32One simple approach would be to create a new function that wraps all your other functions within it. The new function takes in a parameter (string perhaps) that defines the type of operation that you wish to do (e.g. "add", "equal", etc). Then use a javascript switch/case statement to trigger which of your functions to use and return the results.
Let me illustrate it with an example using your code..
