And just the fact that somebody else takes a look at your project -- and I'm sure it's true of other things, too, but it's definitely true in code -- is that somebody else takes an interest in your code, looks at it enough to actually give you feedback and give you ideas.
让别人看一下你所做的项目—— 我想在其他行业也是这样—— 但在编程的时候就更是如此—— 有人对你的代码感兴趣， 仔细研究过，能给你反馈， 给你建议。
