Hellow!

I need to use a variable type definition on an incoming variable type.
See the code below – it was here to define a function call with a number key, but instead, a function with a string key and an unknown data type is defined (see the attached images)

interface IObj { i:number; } // type data
interface IEach {
	each<TT>(p_obj:{[key:string]:TT}, p_fn:(v:TT, k:string) => void); // key string, data IObj
	each<TT>(p_obj:{[key:number]:TT}, p_fn:(v:TT, k:number) => void); // key number, data IObj
}
export function test4() {
	var l_array:{[key:number]:IObj[]}; // declare variable
	var l_each:IEach; // emulate interface instance fo call
	l_each.each(l_array, function(v, k) { v.sort(function(v1, v2) { return v1.i -v2.i; }); }); // ERROR
}

If you swap the function declaration and put the key first: number – then everything works correctly.

interface IObj { i:number; }
	
interface IEach {
	each<TT>(p_obj:{[key:number]:TT}, p_fn:(v:TT, k:number) => void); // key number to move first
	each<TT>(p_obj:{[key:string]:TT}, p_fn:(v:TT, k:string) => void); // key string to move second
}
	
export function test4() {
	var l_array:{[key:number]:IObj[]};
	var l_each:IEach; // emulate interface instance
	l_each.each(l_array, function(v, k) { v.sort(function(v1, v2) { return v1.i -v2.i; }); });
}

Why is this happening? How to fix it?

Gorand,

The problem reported by you is a limitation in TypeScript. I am afraid we cannot fix it at our end.
I suggest you cross post to TypeScript or development related forums like stackoverflow.com for better suggestions from the developer community.

Sorry that we couldn’t assist further.
