# Reduce Nesting
Deep nesting hides bugs in the branches you didn't read.
- **Guard clauses**, handle the invalid/edge cases first and return early. The happy path drops to the left margin.
- **Invert conditions**, `if (!valid) return;` instead of wrapping the whole body in `if (valid) {...}`.
- **Extract**, a nested block doing one thing becomes a named function.
- **Replace flag-then-branch**, return the result directly instead of setting a variable to return later.
Target: no function deeper than 2-3 levels. If you still need more, the function is doing too much, split it.
