Hello sir! I am working to publicly release an augmented version of a previously company internal performance oriented selector library (get.js). Anyway I wanted to make sure I properly credited you for the
.indexOfpolyfill before I finish the initial testing release.Currently the unminified codebase includes:
// Credit : Julien Bouquillon : https://github.com/revolunetIn addition I will be adding a credit section to the read-me once
0.1.0is finished.Let me know if I should include a website link or anything else.
Best,
Daniel
