For the best answer to a question tagged with tips, because this site isn't just about competing with one another, but also about helping each other improve our golfing skills
The shortest infinite for comprehension (self-nomination by pxeger)
While answering Write an infinitely nested generator comprehension, I discovered a way to shorten something you might think to be totally optimal, which felt like a crazy new discovery to make.
s isn't longest first, but ⊇ is by Unrelated String
In Brachylog, s is the obvious builtin for "get all contiguous sublists." The trouble is that you often want to generate the longest sublist first, and s doesn't do that: it starts with all sublists that include the first element. However, Unrelated String realized that ⊇, "get all sublists, not necessarily contiguous," does generate the longest sublists first, and furthermore that the non-contiguous results can be easily removed by combining ⊇ with s. This tip is non-obvious and really useful; I've used it twice already.
Use ₃ and Ḣ for certain length checks by emanresuA
Nomination by @lyxal
This tip has been helpful many times in shaving bytes off my answers. Plus, it utilises some of the lesser-known overloads of things like how ₃ will check to see if a string is of length 1.
Compress your strings and numbers by lyxal
Self nomination
String/number compression is an important part of any modern SBCS golfing language, and Vyxal is no different. This tip gives a comprehensive explanation of the compression utilities available to vyxalers, and it explains the concept of things like "String Compression Codes" and the dictionary of words Vyxal uses.
