Stuck on an issue?

@mcama are you sure about that?

I just did a quick hacky check by logging the ref in a setTimeout and I see the populated ref:

          onRef={ref => { 
            console.log("initial ref", ref)
            setTimeout(() => console.log("timeout ref", ref))
          }}

Remember that refs are mutable, meaning, the reference that current is pointing to may change. But if you try to pull the off current on first render, assign that to a variable, and expect that to change, it won’t work, because you’ll just be assigning that variable to null:

onRef={ref => {
  // Won't work! You'll end up assigning null to a class property
  this.myRefCurrent = ref.current

  // Will work, and myRef's 'current' property will be updated to reflect the current ref
  this.myRef = ref
}}

@terrorpixel Thanks for the example! This helped a lot. Could you explain why you don’t have to declare exampleRef before onRef?
