This Changes JavaScript FOREVER

JavaScript has introduced 11 new iterator helper methods including map, filter, drop, take, every, find, sum, reduce, forEach, and toArray. These methods work specifically with generators and iterators, providing lazy evaluation capabilities. Unlike array methods, iterator helpers don't execute until values are pulled using next(), making them memory-efficient for handling infinite sequences and paginated data. The methods can be chained together for complex data transformations while maintaining performance benefits through deferred execution.
