Five Simple JavaScript Habits That Keep Code Easier to Maintain

A DEV Community article argues that writing JavaScript that merely works is not enough as projects grow, since readability and maintainability matter just as much. It recommends choosing descriptive variable names that clearly convey what they hold, rather than vague labels like x or temp. The piece advises keeping each function focused on a single task and splitting complex logic into smaller, easier-to-test pieces. It also suggests turning repeated code into reusable functions and using error handling, such as try...catch, to manage unexpected inputs and failed operations. Finally, it encourages periodically reviewing finished code for unnecessary complexity, emphasizing that consistent small improvements have the greatest impact.
