Debugging: Listing the "hidden" variables

I believe that there is the concept of a symbol table for variables that are flagged as hidden. These (I believe) can then be used by Espruino internals to cache away data. Is there a way to debug/dump the content of these variables?

Use use trace() - if you want to dig down into something specific then use trace(your_variable).

trace(global["\xFF"]) is probably the stuff you really care about.

Just to add - once you've found the hidden variables you can print them normally, so:
```
setInterval("",1000);
console.log(global["\xFF"].timers);
```
will give you a much cleaner dump of (for instance) active timers.

Perfect. Exactly what I was looking for.

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

```
Your code goes here

Just like Github, a blank line must precede a code block.
