TheTouchList interface represents a list of contact points on a touch surface. For example, if the user has three fingers on the touch surface (such as a screen or trackpad), the correspondingTouchList object would have oneTouch object for each finger, for a total of three entries.

This interface was anattempt to create an unmodifiable list and only continues to be supported to not break code that's already using it. Modern APIs represent list structures using types based on JavaScriptarrays, thus making many array methods available, and at the same time imposing additional semantics on their usage (such as making their items read-only).

These historical reasons do not mean that you as a developer should avoidTouchList. You don't createTouchList objects yourself, but you get them from APIs such asTouchEvent.targetTouches, and these APIs are not deprecated. However, be careful of the semantic differences from a real array.
