public interface ForEachCallback<T>
T forEach(Object thisArg, Value element, int index, Array<?> array)
If a thisArg parameter is provided to Array.forEach(ForEachCallback, Object)
, it will be used as the thisArg parameter for
each callback invocation.
If thisArg is undefined or null, the this value within the function depends on whether the function is in strict mode or not (passed value if in strict mode, global object if in non-strict mode).
