I am currently a web developer at JS-Dev Corp, where I regularly work with JavaScript on diverse web development projects. One core principle I live by is always considering other developers, or even future versions of myself, who might need to maintain or upgrade my code.
For this reason, I prioritize clean and organized code using modular programming. I separate my code into distinct modules based on functionality, making it easier to debug, test, and understand.
Another crucial part of code maintainability is testing. I use automated testing tools like JUnit and Selenium to regularly test the code for regressions and ensure overall quality.
Last but not least, I rigorously adhere to standardized documentation practices. I use JSDoc for API documentation, to help any future developer understand the project. Including the project structure, data models, class and function definitions, and even individual lines of code, this, in turn, enhances the maintainability of my code.
