In this summary, I list some of the things that have helped me in my career. It reads fast, but applying them well can take a lifetime. I have been developing applications for almost 15 years, and still, sometimes, I have to stop and think in the essential parts of this profession.
Take the code and break down big pieces of code into small functions.
If by the time you leave work you haven’t solved the problem. Turn off the computer and leave it for the next day. Don’t think about the problem anymore.
YAGNI principle: don’t codify more than you’ve been asked to. Don’t anticipate the future, and just create something that works as soon as possible. Code only the necessary parts to solve the current problem.
You don’t need to know everything, nor all the existing frameworks. The most significant thing is to have a good base. Know the language in depth before starting with a Framework and learn fundamental things like the SOLID principles or how to write clean code.
