What does "formatter" mean in programming?
formatter 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
A tool that automatically rewrites source code to conform to a consistent style: indentation, line length, quote style, spacing. Unlike linters (which flag issues), formatters fix them automatically. Common formatters: Prettier (JS/TS), Black (Python), gofmt (Go). Running a formatter on save eliminates style debates in code review.
Example
"We run Prettier as a pre-commit hook — all code is auto-formatted before it can be committed."
