I'm trying to find a substring in a title, but I don't know if I should go with regexp or strings library. I'm not looking for complex stuffs, only for a simple string match. I only need to be the most efficient way since I'm gonna use it on a slice, ty!

dgryski:Regardless of the solution you should benchmark it. You may think that a solution is fast or slow but the reality is that until you measure its pretty much the fastest and the slowest at the same time.

shark1337:The regexp package is more powerful, but slower. For slices use https://golang.org/pkg/bytes/
danredux:I'm only looking for something like this: hasSubstring("my own text", "own") bool {} but it has to be the fastest way ;)
jerf:strings.Contains
Can confirm. I just read the source code and it is well-tuned, not just a naive algorithm. You might be able to outdo it in very specific cases with a really good algorithm but it won't be easy.
