access variable in fadeout callback

Question

How can I access test inside the fadeOut() callback?

  slide(test) {
    console.log("test before callback: ", test);
    $(".class").fadeOut(1000, function(test) {
      console.log("test after callback: ", test);
    });
  }

slide()

test before callback:  Proxy {dispatchConfig: {…}, _targetInst: ReactDOMComponent, isDefaultPrevented: ƒ, isPropagationStopped: ƒ, _dispatchListeners: ƒ, …}
45my.js:17 test after callback:  undefined

i.e.: `$(".class").fadeOut(1000, function() { console.log(test); }` — freedomn-m, Jun 19 '19 at 18:21

Remove test from the callback parameter as that is shadowing your outer most test argument.
