Remove unnecessary null/undefined checks when you already have sufficient validation in place, and use proper type guards instead of type assertions for better null safety.

When you’ve already validated that a value is truthy or non-null, avoid redundant checks that add noise without providing additional safety. Similarly, prefer type guard functions over type assertions to maintain proper null safety.

Examples of improvements:

This approach reduces code complexity while maintaining robust null handling, making your code both cleaner and safer.
