Frequently asked questions
Why do I get a syntax error?
The minifier needs valid JavaScript. A missing bracket or an unfinished statement will stop it, so run the code through a linter first.
Does minifying hide my code?
It makes it harder to read but not secure. Anyone can reformat minified code, so do not put secrets in front-end scripts.
