Early return is a design patter that combines with the happy-path design pattern. When a function deviates from the happy path, we include a return inside the deviation so that the function interrupts.

1if x <= 0 {
2    fmt.Println("Nope, x is zero or negative")
3    return false
4}

It’s clear that if the function gets past this point, the condition must have been false, or we would have returned already.

This often makes else statements pointless
