In this chapter, we looked at some of the more essential concepts that go into software development that have nothing to do with the actual coding. Even if we are not working on large-scale, professional projects, we should still version control our code, write tests to verify that the code does what it is supposed to, and work iteratively.
We began by learning that version control systems are a great tool that will help us not only be able to go back in time to an earlier version of the code, but also help us share our code with other developers in our team.
Then, we saw that to verify that the code we have written is doing what it is supposed to, we need to test it. In this case, we have something called unit tests and integration tests that we should perform to make sure that the application produces the correct result and that the new code does not produce any side effects, which would produce an undesirable result for a code that worked successfully in a previous...
