TypeScript: Assign value to field name in variable

Question

I need to

type A {
  f1: string;
  f2; string;
}

By other side I have a variable contains the field name:

let fieldName: string = "f2";

I'd like to create an object using fieldName:

{"content of fieldName": "sdf"}

Any ideas?

As of ES2015 you can use computed properties.

For your example that would mean:

{ [fieldName]: "sdf" }

Just use {[fieldName]:'sdf'}. Here is a blitz
