Filter ( nums , func ( n , _ int , _ [] int ) bool { return n % 2 == 0 }) doubled := array . Map ( even , func ( n , _ int , _ [] int ) int { return n * 2 }) // [4, 8] Enter fullscreen mode Exit fullscreen mode Or chainable, if you prefer that style: arr := array . Array [ int ]{ 1 , 2 , 3 , 4 , 5 } result := arr . Filter ( func ( n , _ int , _ [] int ) bool { return n % 2 == 0 }) .…
