If you read “One Billion Row Challenge in Golang” or how to write faster Go code, it’s now a great time to read about how to write cleaner code. This article shares key principles for writing clean and effective Go code.

Two phrases that resonate with me a lot from this article:

1. 🚀 github.com/jarcoal/httpmock — A library that makes it super easy to set up mocks for HTTP requests. You can register responders for specific URLs, handle different request methods, and even use regular expressions for more complex patterns.

2. 🌟 github.com/alecthomas/chroma — A handy syntax highlighter. It takes your code and transforms it into nicely formatted HTML or ANSI-colored text

3. 🌎️ github.com/nicksnyder/go-i18n — If you want to internationalise your program, go-i18n can help. It has support for message files and pluralised strings in 200+ langauges.
