Create strongly typed array of arrays in TypeScript

Question

In a language like C# I can declare a list of lists like:

List<List<int>> list_of_lists; 

Is there a similar way to declare a strongly typed array of arrays in TypeScript? I tried the following approaches but neither compiles.

var list_of_lists:int[][]; var list_of_lists:Array<int[]>; 

Answer 1

int is not a type in TypeScript. You probably want to use number:

var listOfLists : number[][];
