What does "complexity" mean in programming?
complexity is one of the most common terms in software development. This guide explains what it means, how it is used in practice, and why it matters, with real examples from the developer world.
Definition
The degree of difficulty in understanding or changing a system. High complexity slows development and increases bugs. Measured formally through cyclomatic complexity (number of independent code paths) or cognitive complexity (how hard code is to read).
Example
"This function has cyclomatic complexity of 15 — break it into smaller pieces."
