Code Formatter

The everyday use is reading something you did not write. A minified bundle you are debugging in production, a config file that arrived as one line, a snippet pasted out of a chat client that lost every newline. Making it readable is the first step of understanding it.

For your own projects, formatting should not be a manual step at all. Prettier, gofmt, rustfmt, or black wired into a pre-commit hook removes formatting from code review entirely, which is done purely to stop reviewers spending attention on indentation instead of logic.
