Developers often strive for efficiency, but sometimes, optimizing too early can lead to more problems than solutions.

The Danger of Early Optimization

Optimizing code before understanding its performance bottlenecks can waste time and introduce unnecessary complexity. It's tempting to micro-optimize, but it's crucial to identify the actual performance-critical sections first.
