Announcing LibreJS 4.6!

GNU LibreJS aims to address the JavaScript problem described in Richard Stallman's article The JavaScript Trap[1]. LibreJS is a free add-on for GNU IceCat and other Mozilla-based browsers. It blocks nonfree nontrivial JavaScript while allowing JavaScript that is free and/or trivial.

Unix shells have always meant to be used interactively, and thus have lots of builtins and first class syntax for dealing with processes that are lacking in general-purpose languages like Python.  Historically, sh probably has more functions in common with job control languages than anything else.  Python, on the other hand, is a general-purpose language in the tradition of ALGOL.

The fact that both languages are typically implemented using a user process REPL doesn't change the fact that they have different lineage and purposes.
