Question

I have dictionary objects in my c#. but I need to migrate to typescript. I am new to typescript. I really don't know, how to use dictionary in typescript.

C#:

 LengthsByCountry = new Dictionary<string, int>
            {
                {"AD", 24}, {"AL", 28}, {"AT", 20}, {"BA", 20}, 
                {"BE", 16}, {"BG", 22}, {"CH", 21}, {"CY", 28},

You can do something like this:

let lengthsByCountry: { [key: string]: number; } = {};

Then initialize the items:

lengthsByCountry["AD"] = 24;

There's no direct mapping for the inline initialization at present, as far as I know.
