What is the best way to set up an empty {[key: string]: string} object in TypeScript?

interface a {
    d: {[key: string]: string}
}

class a {
    d = {}
}

The error message returned is as follows:

Subsequent property declarations must have the same type. Property 'd' must be of type '{ [key: string]: string; }', but here has type '{}'

let v: {[key: string]: string} = {}

No warning or error is raised for this declaration

What am I overlooking?

Answer №1

Both your interface and class share the name a. It would be best to rename one of them to avoid confusion. Consider using this structure instead:

class b implements a {
    d = {}
}
