Daily Productive Sharing 475 - How to Write Better Code?
One helpful tip per day:)
(下附中文版)
Alex Ewerlöf, a software engineer with 20 years of experience, has summarized twenty programming insights. The following have been very helpful to me.
- write code not for machines to read, but for your future self and for your collaborators to read.
- deprecate yourself from the code and be prepared to speak about it when you're done, rather than owning it all the time.
- copy and paste code is easy to copy bugs, learn to reuse code, not copy and paste.
- keep learning, if you think you're already a master, it means you're not learning enough.
- write more pure functions and more tests.
- understand the problem before writing code, understand the business before writing code.

Alex Ewerlöf 是一位有着20年经验的软件工程师，他总结了二十条编程感悟。以下这些对我帮助非常大：
- 写代码不是写给机器读的，而是写给你未来的自己，写给你的合作者读的；
- 将自己从代码里剥离，写完就要准备讲这些代码托付给其他人，而不是一直拥有这些代码；
- 复制粘贴代码很容易复制 bug，要学会复用代码，而不是复制粘贴；
- 保持学习，如果你觉得自己已经是大师了，那说明你学习得不够；
- 多写纯函数，多写测试；
- 理解问题之后再写代码，理解业务之后再写代码。
