Description copied from class: ScriptArray

This function deletes all elements in the range from [start..end[. This is equivalent to shifting the whole array, starting with element index end, by end-start positions to the left. Can be used by e.g. Array.prototype.splice;

Specified by:

removeRangeImpl in class ScriptArray
