this is part of my code:
const myObj: object = {} const propname = \'propname\' myObj[propname] = \'string\' <
const myObj: object = {} const propname = \'propname\' myObj[propname] = \'string\'
You have to define what kind of index type the object has. In your case it is a string based index.
string
const myObj: {[index: string]:any} = {}
