What is a good code complexity?
Cyclomatic complexity is a simple measure of complexity in an application or routine. For most routines, a cyclomatic complexity below 4 is considered good; a cyclomatic complexity between 5 and 7 is considered medium complexity, between 8 and 10 is high complexity, and above that is extreme complexity.
How is complexity of code calculated?
Here are some of the metrics used to measure code complexity
- Source Lines of Code (SLOC) – It counts the number of lines in the source code. It is the most straightforward metric used to measure the size of the program.
- Cyclomatic Complexity – This measures how much control flow exists in a program.
How can we avoid complexity?
Over time however, it’s important to do all seven so that simplicity becomes a core capability of your organization and not just a one-time project.
- Clear the underbrush.
- Take an outside-in perspective.
- Prioritize, prioritize, prioritize.
- Take the shortest path from here to there.
- Stop being so nice.
Why is it important to reduce code complexity?
Given that, by reducing code complexity, you reduce the risk of introducing defects; whether they’re small or large, slightly embarrassing or bankruptcy-inducing. When the risk of potential defects is reduced, there are fewer defects to find—and remove.
How does the complexity rule work in JavaScript?
This rule is aimed at reducing code complexity by capping the amount of cyclomatic complexity allowed in a program. As such, it will warn when the cyclomatic complexity crosses the configured threshold (default is 20). Examples of incorrect code for a maximum of 2:
How does the complexity rule in ESLint work?
This rule is aimed at reducing code complexity by capping the amount of cyclomatic complexity allowed in a program. As such, it will warn when the cyclomatic complexity crosses the configured threshold (default is 20).
Is there a limit to cyclomatic complexity in JavaScript?
Limit Cyclomatic Complexity (complexity) Cyclomatic complexity measures the number of linearly independent paths through a program’s source code. This rule allows setting a cyclomatic complexity threshold. Rule Details. This rule is aimed at reducing code complexity by capping the amount of cyclomatic complexity allowed in a program.
