Remove function In ReactJs in mobile view

Suppose I have a component that has two functions which are run when the app is started so when I switch app in responsive width and that width is mobile so i want to run only one function in that the second one has to be removed

does anyone can help??

>Solution :

Just get window width and set if statement.

const width = window.innerWidth

if (width === 400) {
  runFunction()
}

or

const width = window.innerWidth

const runFunction = () => {
  if (width === 400) {
    // ...function logic
    return
  }
   
  return
}
