I often write some code, then get an error, change it, and see a different error. Does this mean that the first error is fixed and that I only have a new error because of what I just changed? or just that this new error is more "pressing" than the first? How can I find out?
我经常写一些代码，然后得到一个错误，改变它，看到一个不同的错误。这是否意味着第一个错误是固定的，而我只是因为刚刚更改的内容而出现了新的错误？或者只是说这个新错误比第一个错误更“紧迫”？我该怎么知道？

It could be both. Most times when you fix the first error you should just be seeing a notice for the error that follows. However, if your fix was not correct or was messing with previous snippets, you could be causing errors out of the blue.
它可能都是。大多数情况下，当您修复第一个错误时，您应该只看到后面的错误通知。但是，如果您的修复程序不正确或者正在弄乱先前的代码段，则可能会导致错误。
That is why techniques like testing are important. If such logic errors occur, your test suite is there to save the day.
这就是测试等技术很重要的原因。如果出现这样的逻辑错误，那么您的测试套件可以节省一天的时间。
