Description:

I used to be under the
impression that youtube-dl executes proprietary JavaScript, but I now
understand that it only *parses* the JavaScript to find the URL for some
videos. It doesn’t actually run the JavaScript, so it’s not a freedom
issue.

Youtube-dl only executes regular expressions [0][1][2]

you also remove the files that are just for testing [3][4][5][6][7]
and when compiling the program with libretools the test files are not placed[8]

I have consulted with other programmers and we have reached the same conclusion. Youtube-dl does not execute JS non-free, it only extracts the JS to read through python the URL‘s of some videos.[9][10]

The issues that I see with youtube-dl are rather in their form of development because it changes at every moment
