Go Project Source Code Analysis: Schedule Job Library "cron"
There are many excellent open-source projects on GitHub, where the code is transparent and available to everyone. As software developer, we can learn a lot from them including software engineering, unit testing, coding style standardization, etc. We can even find issues by looking into their code, and submit pull requests to contribute to tech communities. Today we are going to dig into the source code of a popular Golang open-source project on GitHub, robfig/cron, which is small and with clear annotations, and is very suitable for new developers to learn how to read and analyze source code.
