From what I’ve gathered, the smartest developers often share certain traits and habits that set them apart. One key takeaway is the importance of writing unit tests and being thorough in code reviews. This ensures that the code is robust and reliable, and catches any errors or bugs early on.

Lesson 1: Write Unit Tests Writing unit tests is crucial in ensuring that the code works as expected. It’s not just about getting the code to work, but also about making sure it’s maintainable and scalable in the long run. One developer, Don, emphasized the importance of writing tests for every feature created. This not only ensures that the code works but also helps in catching any errors or bugs early on.

Lesson 2: Be Thorough in Code Reviews Code reviews are an essential part of the development process. It’s not just about rubber-stamping code, but about making sure that the code is of high quality and meets the required standards. One developer, Parker, emphasized the importance of being meticulous in code reviews. He would run the code locally, test the functionality, and ask clarifying questions to ensure that he understood the code.

Lesson 3: Align with Business Goals It’s essential to align the development work with the business goals. One developer, James, emphasized the importance of understanding the business context and ensuring that the development work supports the business goals. This involves understanding the requirements, identifying the key performance indicators, and ensuring that the development work meets those requirements.

By following these lessons, developers can improve the quality of their code, reduce errors and bugs, and ensure that their work aligns with the business goals.
