Go processes data efficiently through streaming API s such as Map/Filter/ForEach

What is stream processing If you have Java experience, you will be full of praise for java8 Stream, which greatly improves your ability to process collection type data. int sum = widgets.stream() .filter(w -> w.getColor() == RED) .mapToInt(w -> w.getWeight()) .sum(); Stream enables us to support ...
