gef VS UglifyJS2

There is also GEF, which is widely used by the reverse engineering and CTF community.

If you are on Linux, install GEF and be happy.

If you are in linux, I recomend none of them (haha) because you should get more used to GDB a little bit. You just need to install some good visualizers likes GEF, for example.

https://github.com/hugsy/gef, https://hugsy.github.io/gef/, https://hugsy.github.io/gef/commands/context/ ("Values in red indicate that this register has had its value changed since the last time execution stopped.")

The attached debugger is not just raw GDB but is using https://hugsy.github.io/gef/ to make debugging less of a pain. It's still not perfect but helps plenty already.

I still struggle with GDB but my excuse is that I seldom use it.

When I was studying reverse engineering though, I came across a really cool kit (which I've yet to find an alternative for lldb, which would be nice given: rust)

I'd recommend checking it out, if for no other reason than it makes a lot of things really obvious (like watching what value lives in which register).

LLDB's closest alternative to this is called Venom, but it's not the same at all. https://github.com/ovh/venom

Minification involves removing unnecessary characters, whitespace, and comments from code files. It helps reduce HTML, CSS, JavaScript, etc., file sizes without compromising functionality. Removing redundant elements makes these HTML, JavaScript, and CSS files smaller. Since smaller code files need less internet traffic to transfer, they load faster. Utilizing tools like UglifyJS, Clean-CSS, and HTMLMinifier enhances this process of code reduction. They analyze the code, remove redundant code, and generate optimized files for deployment.

Example: You've got a main.js file that's as long as a Tolstoy novel. Fix: Use tools like UglifyJS or Terser to minify your code. They'll squeeze out all the unnecessary bits and give you a sleeker, faster-loading file.

Minification: UglifyJS, Terser

There are a bunch of libraries that do this, but my current go to is Uglify: https://www.npmjs.com/package/uglify-js

There are many minifiers such as terser and uglify. But, because minifying also require to parse the JS, it is actually possible to use esbuild and SWC to minify the code. Here's a benchmark of the main minifiers.

In my understanding, UglifyJS 3 is the most popular JavaScript minifier tool presently -- it has a very high weekly download too. And as per the official documentation, it supports ES6.

I'm thinking reverse-engineered uglified js code (https://github.com/mishoo/UglifyJS) is not as impenetrable as code from reversed engineered wasm binaries? The element of plausible deniability is much more potent though, for the nefarious actor on the other side.

Program: uglifyjs Arguments: $FileName$ -c -m -o $FileNameWithoutExtension$.min.js

Apart from terser, you can also use uglify-js to compress or minify javascript.
