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. - Source: dev.to / over 1 year ago

Even without tools it looked a bit weird, all files in source without minification costs us 27k, its something not needed inside, and if you unpack it with something like https://beautifier.io/ you will see:. - Source: dev.to / 3 months ago

I can go through the functions that I have wrote in here. Go to js beautifier and paste in the code for easier viewing while reading this. Source: 12 months ago

View source and get the main javascript file https://musicforprogramming.net/client/client.bc21fa59.js then stick it in a beautifier https://beautifier.io/ then grab the most likely looking function, the easiest way is to delete everything that's obviously nothing to do with the animation, then what you have left is the code you want.

Sprite list from the randomizer can be found at https://alttpr.com/sprites/ with links to the zspr files (copy/paste the output into https://beautifier.io/ to make it more readable). Source: almost 2 years ago

You can use an online service like beautifier.io to try to clean it up a bit. There is no way to get the original human readable JS back though. If you are interested in reading source code, you might have more luck looking at repos on GitHub, which will not be minified. Source: almost 2 years ago
