Understanding overhead in your code
Published on 11/25/2025
Today I learned more about a common concept in development called overhead.
Overhead is everything your code or system needs to do in addition to the main task. It is the extra work that happens behind the scenes.
For example
- Extra renders in React
- Unnecessary calculations
- Repeating logic
- Heavy libraries for simple tasks
- Too many API calls
- Code that is harder to maintain than it needs to be
All of this adds weight. It slows things down and makes the project more complex than necessary.
Good code tries to reduce overhead.
It does only what it needs to do, in the simplest and clearest way possible.
Learning to see overhead is part of becoming a better developer. It helps you write cleaner code, faster features, and apps that feel better to use.
