Hi @Freek, thank you very much for this excellent video demonstrating the benefits of early returns. I recommended it to a junior developer that I am mentoring. If you don't mind, I'd like to add one more tip to what you have already said. I reverse the
ifcondition to gain the benefit from an early return in thepublish()method. What I typically do is include a redundant negative boolean method. So instead of writingif(! $this->isPublishable()) { return;}, I introduce a function like the one below:and call that in the
publish()method instead of negating the condition inside the main function. It is not a hard-and-fast rule, but I have found that it helps with code readability significantly.Love from, Malawi!
