Typescript: bracket notation property access

Question

I\'d like to access typed object with bracket notation like this:

interface IFoo {
    bar: string[];
}

var obj: IFoo = { bar: [\"a\", \"b\"] }
var name = \         


        

Answer 1

I added it as a separate interface because i need to keep original..

export interface IIndexable {
  [key: string]: any;
}

and referencing it when needed

getEditDate(r: IRestriction, fieldName: string) {
    ...
    value={(r as IIndexable)[fieldName] as Date}

works well. i will update if i find a way to shorten it
