@arun-cm Fewer LoC :)

That being said, you lose potential autocomplete when using the lib in the console thus reducing the developer experience :(
Also, no error handling on this Proxy on missing method calls (easily fixable)

@brandonmcconnell - sure, why not:

EDIT: aww, doesn't work :(

Can anybody explain this code to me? Everything is so innocently looking for somebody who doesn't understand much js, that I'm confused.

@sukiletxe: There is nothing malicious going on in this part of the code. This is simply the alibi for including it in other packages: easy log colors, hooray! @josejbreijo described above where the funny business is hidden:

@josejbreijo […] The malicious JS script mentioned in the article (which I believe is what you're referring to) is hidden in a file under lib/ directory, which was not included on GitHub, but could (hypothetically) be published to an npm package - hence, the sources didn't match, and you simply wouldn't find the malicious code here. The source above is... literally what it is :).
