how does typescript cast any[]

I have a class 

class List<T>

which contains:

private _items = [];


public items() {
    return this._items;
}

why does this work

private loop() {
    for (var x of this._items) {
    }

but this doesn't

 private loop() {
    for (var x of this.items) {
    }

with the error given as: Type '() => any[]' is not an array type or a string type.

You're just missing the method invocation on this.items - you want this.items() instead, which will return the array, rather than using the method itself as the target of iteration.
