Snippets allow us to expand repetitive code without the need to type it entirely or rely on a menu of mostly irrelevant autocomplete options. They are quite useful and can dramatically increase the speed with which we produce functional prototypes. The longer we are busy with typing, the less time we have to develop our concepts. We start to think of which key we need to press next, instead of thinking in ideas, layering them on each other and focusing on the next step of the execution. It seems that snippets are still underutilized despite their availability in various editors.
Even if snippets have some downsides, they can still be useful in our daily work. You could try them out and see whether they work for you. If so, happy tabbing.
