Error In Declare Multiple Dimensional Array In TypeScript

In my app, I need to define an element like: commandsList:[RegExp, string, string]; but when I tried to push the array elements into it, as below: public registerCommand(command:R

Solution 1:

Correct me if I'm wrong, but it looks like you're trying to push an object, where the array expects a RegExp | string type.

Solution 2:

I found the best way is to use interface like:

interface ICommand {
   regexp: RegExp;
   callback: Function;
}

then defining the array as:

let commandsList: ICommand[];
