Keep in mind Lisp predates the Internet by many decades. The Lisp tradition is to leverage the expressiveness of the language to quickly create functionality that would be included as libraries in other languages. If you need an algorithm implemented, just do it and if it turns out you need it hyper-optimized and able to handle the pathological cases you look for someone who has something like that. The JavaScript tradition (once NPM became a thing) is almost the opposite, look for a library first, and if you can't find one then consider making it yourself and posting it for others.
