8 min readIn Go, you cannot directly return data from a for loop as you do in other programming languages. The for loop in Go is primarily used for iteration and control flow. However, you can use other techniques to achieve your goal.One common approach is to declare a variable outside the for loop and update it within the loop. You can then return this variable after the loop has completed.
