I hope everyone is having a good holiday season. I've been working on
edbrowse over the past couple of days, but fooling around with experiments
that may or may not lead somewhere. Well that's what led to the use of
esprima and escodegen for deminimizing code, which has been wonderful, so
it leads to great things sometimes.
So the project I've been playing with recently is called JS Interpreter.
https://github.com/NeilFraser/JS-Interpreter.git
https://neil.fraser.name/software/JS-Interpreter/docs.html
A demo is here:
https://neil.fraser.name/software/JS-Interpreter/index.html
It's a sandboxed javascript interpreter written in javascript. It has a
step(). It remains to be seen if it will lead to insights that lead to
real work, but it certainly is fun and informative. Basically it's like a
javascript debugger, with no need for a bloated GUI like firebug,
everything can be examined using ok(), and even the code of the debugger
itself is accessible to modify or echo both the subject-matter javascript
and the debugger's-own javascript. I love it!
Pull it up if you feel like relaxing with something edbrowse-related yet
potentially just for fun. You may have ideas for how we can use it.

Well I wonder if the interpreter can understand our side effects, like setters and such, like setting form.whatever.value calls a c function that does something etc.
If it can't incorporate that then I don't think it would be very useful.
We do need something like that though; there are some sites that just hang in js, we don't know why and we don't have an error to go on.
I'll post a url the next time I run into one of these sites.
