Nested loops can slow down innovation

This code insight detects loops within a loop (for, do, while, foreach, etc.). Depending on thresholds observed in the benchmark of thousands of applications and billions lines of code, Highlight accounts penalty points to the given scanned files.

Why you should care

For code readability and performance, nested loops are frequently considered as a bad practice. In many cases, there’s a much faster and less wasteful way to accomplish the goal you’re trying to achieve.

Business Impacts

Complex code can slow down innovation


CAST recommendations

Consider refactoring your code by avoiding the use of nested loops.
