Is it possible to specify one single type for all elements of an object?

Question

typescript

Let's say there is an object
obj = {};
it will contain Ne number of elements.
Is it possible to somehow specify for this object that all element values ​​in it will be of the same type,
for example Object or string, without specifying each element of the type:

obj = {
    abc: <string>'abc',
    def: <string>'def'
    ....
}

Is there any way, through the interface, there, or something else?

Answer 1

Found the answer

obj: {[id: string]: string} = { 
    abc: 'abc',
    def: 'def'
}
