And you can therefore we have fun with limited processors and ultizing minimal processor chip i have much programming language whose threading requires much more memory and decreases the brand new performance of our system. And this, to get over such as state Golang was created in such an excellent method in which rather than having fun with threading it spends Goroutine, that is just like threading but eats very smaller recollections.
