linting

linting — Linting is the automated process of analyzing source code to find and flag potential bugs, style inconsistencies, and deviations from best practices before the code is executed or shipped.

In simple English

In tech teams, a linter is a tool that scans your code line by line to catch common mistakes early. This includes things like unused variables, syntax errors, inconsistent spacing, and incorrect naming conventions. Linting happens during development and is often integrated into the build pipeline or version control workflow. Teams run linting to maintain code quality, ensure consistency across the codebase, and reduce the number of issues caught later during code review or testing. Popular linters include ESLint for JavaScript, Pylint for Python, and Checkstyle for Java.

Understand what linting is, why it matters, and which linting tools are best for your programming language.

Say it like this

  • Run linting on your code before pushing
  • The linting failed because of formatting issues
  • We need stricter linting rules for this project

Use it at work

Code review

  • The linter is failing. Can you fix the warnings?
  • Let's add a linting rule for unused imports.

Setup

  • Run lint before you push.
  • Linting runs automatically in CI.

Team rules

  • Let's agree on linting rules for the new repo.
  • Disable this lint rule only with a comment explaining why.

Don't say this

✕We use linting to test if the application works correctly.
✓We use linting to check for code style issues and potential bugs, not to test functionality.

Linting finds style and syntax problems, not whether code actually functions. Testing does that.

More about linting

Real examples(3)

  • in a standup

    "I finished the feature yesterday, but linting caught several unused imports that I need to clean up."

  • in a code review

    "The linting errors need to be fixed before this PR can be merged into main."

  • in a team meeting

    "We should configure linting in our CI pipeline so that code quality checks happen automatically."

More mistakes(2)

Handle with care. Linting is a noun; do not confuse it with testing or formatting. It checks for code style issues and potential errors, not functionality.

  • ✕The linting formatted all our code.
    ✓The formatter reformatted our code; linting just reported the issues.

    Linting reports problems; formatting tools fix them. They are separate processes.

  • ✕We are linting the application.
    ✓We're running linting on the code.

    You lint code or files, not entire applications. The verb form is less common than the noun.

Other forms(3)

  • linting noun

    "Linting is part of our development workflow."

  • linter noun

    "Our linter flags any variable that is declared but never used."

  • lint verb

    "Please lint your code before submitting the pull request."

Similar words(3)

  • code analysis · Broader term that includes linting but also covers other analysis methods
  • static analysis · More formal term for analyzing code without running it; linting is a type of static analysis

  • runtime testing
  • dynamic analysis

Questions(5)

What does linting mean in software engineering?
Linting is an automated process that scans your source code to find and report potential bugs, style violations, and code quality issues before the code runs. A linter is a tool that performs this analysis without executing the code. It catches problems like unused variables, syntax errors, and inconsistent formatting early in development.
How do you use linting in a sentence at work?
You can say things like: 'Run linting before pushing your code,' 'The linting found three warnings,' or 'We should enable linting in our build pipeline.' The most common usage is 'run linting on your code' or 'linting errors.'
Is linting formal or informal?
Linting is neutral and professional. It is used in both formal documentation and casual team conversations. You will hear it in standup meetings, code reviews, documentation, and job interviews equally.
What is the difference between linting and formatting?
Linting reports style and potential quality issues but does not change your code. Formatting (or auto-formatting) automatically fixes those issues. Many teams use both: linting identifies problems, and formatters like Prettier or Black fix them automatically.
What are common linting tools?
Popular linting tools include ESLint (JavaScript), Pylint (Python), Checkstyle (Java), RuboCop (Ruby), and golangci-lint (Go). Most modern IDEs also have built-in linting support or plugins.
