Nested loops slow down your code.
If you have two lists with 1,000 items each, a nested loop runs 1,000,000 operations. This kills your speed.
The Slow Way: You loop through one list inside another list. Your computer works too hard as your data grows.
The Fast Way: Use a Map or a lookup object.
You turn one list into a Map first. Then you loop through the second list once. This reduces your work from millions of operations to just a few thousand.
Why you should change your approach:
- Performance: Your app stays fast with large datasets.
- Scalability: Your code stays fast as your user base grows.
- Maintainability: Cleaner code is easier to read and fix.
Stop using nested loops for mapping. Use hash maps instead. This keeps your software fast and efficient.
