Frequently asked questions
Is minified JavaScript still readable?
Not easily. Minification is meant for production delivery, not for reading or debugging, so keep your original source file for development.
Can minifying JavaScript break my code?
A good minifier preserves functionality while shortening the code, but code relying on unusual patterns like exact whitespace-sensitive strings should be tested after minifying.
