Typescript generic state change function type casting error

Question

I\'m creating a generic function to change the state.

The error message:

TS2345: Argument of type \'() => { [x:string]: string }\' is not assignable          


        

Answer 1

There are a few solutions:

 this.setState({ [name]: value } as Partial)

Or

 this.setState({ [name]: value } as Pick);

There is an open issue in git, take a look: cannot setState with dynamic key name type-safe
