Gems are the things we love, and warts are the things we don't. On today's episode, Kris is joined by the hosting panel of Ian, Matt, and Dylan and they are talking about the gems and warts of Go. From defer, to net/http, to vanity URLs, to modules, we cover around 30 topics! To prevent our listeners/viewers from returning an E_TOO_MANY_UNPOPS error, we didn't include the Unpopular Opinions segment (there are plenty throughout the episode). We hope you enjoy this tangent filled episode. Have a gem or wart you agree/disagree with or think we missed a few? Let us know on social media or in the comments!
Thank you so much for listening. Happy listening!
