Parameter implicitly has any type in RN typescript

Question

I have the following code in my RN application.

handleTextChange = e => {
  this.setState({ value: e })
}

I use TS and this says, "parameter 'e' implicitly has 'any' type".

How can I solve this? How can I set a type to 'e' here?

Answer 1

You can provide a type annotation for e in cases where it can't be inferred:

handleTextChange = (e: Event) => {
  this.setState({ value: e })
}

I've used Event for the purposes of the example, but you can use whichever type is appropriate.
