On the webpack-obfuscator NPM page, there are a couple of examples with this syntax:

new WebpackObfuscator ({ rotateStringArray: true }, ['excluded_bundle_name.js'])

and

new JavaScriptObfuscator({ rotateStringArray: true }, ['abc.js'])

in plugins section of webpack config

Questions:

1. Why plugin written as "WebpackObfuscator" in the first example and "JavascriptObfuscator" in the second? What and is there a difference?

2. Option "rotateStringArray" used in both examples. But in README of javascript-obfuscator repo there is no such option, but "stringArrayRotate" instead. Is there an error? Or syntax for some options is different?

3. In my project, there is "webpack-obfuscator": "^3.5.1" as dev dependency in package.json. But no "javascript-obfuscator" line (I used someone else's boilerplate). Should I install "javascript-obfuscator" as dev dependency also? (obfuscation seems to work alright, but I'm not sure that all options are working)

Please help
