When people reach for this tool

Understand code that arrived as one long line

Library builds and downloaded snippets are unreadable until they are indented.

Spot an accidental duplicate block

A dense file hides a copy-pasted section; indentation makes the repeat obvious.

Follow the structure of unfamiliar code

Braces and indentation show the shape of a function before you read a single statement.

Practical tips

Always keep a copy of the original. If the code relies on automatic semicolon insertion, formatting can in rare cases change how it parses.
Comments and string contents are preserved, so a file with a long template literal will still be hard to read.

What you get

Format and minify in one place
Strings and comments kept safe

Is formatting risky for JavaScript?

Very slightly, because of automatic semicolon insertion. In practice it is safe for normal code, but keep a copy of the original before formatting anything important.

Does it minify as well?

There is a separate minify action for that. Formatting is for reading, minifying is for shipping, and they serve opposite purposes.
