Coding tips & best practices

Practical habits for writing code that's cleaner, easier to read, and easier for the next person (probably you) to maintain.

  1. Use meaningful variable names

    Choose descriptive names instead of single letters — future readers shouldn't have to guess what a value represents.

    Goodlet userAge = 25;
    Avoidlet x = 25;

  2. Keep your code DRY

    DRY means don't repeat yourself. If you're copying the same logic into a second place, pull it into a function and reuse it instead.

  3. Add comments wisely

    Use comments to explain why you made a decision, not what the code does — the code already says what it does.

  4. Use consistent formatting

    Steady indentation and spacing make code easier to scan for everyone who touches it, including you in six months.

  5. Break code into functions

    Small, single-purpose functions are easier to test, reuse, and reason about than one long block doing everything at once.

  6. Test your code regularly

    Test small pieces as you build rather than writing everything up front and debugging it all at the end.

  7. Keep learning

    Languages, tools, and standards keep moving. Regularly revisiting them keeps your code — and your instincts — current.
