5 Habits That Separate Junior Devs From Senior Engineers
Small ways to write clearer code, ask better questions and make each project easier to maintain.
1. Read before you rewrite
Trace what the code does before changing it. Follow the inputs, state and output. A small change that respects the existing structure is often easier to review than a large rewrite made without context.
2. Make the problem smaller
Reproduce a bug with the fewest steps possible. Write down what you expected and what happened. Remove unrelated assumptions until you can point to the behaviour that needs to change.
3. Name things for the next reader
A clear name carries an explanation. Prefer a function that describes its action and a variable that describes its value. Comments work best when they explain a reason that the code cannot show.
4. Finish the edges
Consider loading, empty data, errors and keyboard use. These moments are part of the product. A finished feature handles them with the same care as its ideal state.
5. Explain your decisions
Good collaboration includes context. Describe what changed, why you chose that approach and what limitations remain. Keep a small record of what you learned so your next project starts with better questions.
Progress starts with a little curiosity, followed by a little practice.
