Asp Forum - Development/debugging tools?

Having another go at mastering JavaScript - the first time for a while
I'll have tinkered with it. I do have a programming background, and I'd
like to use a development/debugging tool. What's available these days,
and what's value for money?

That mostly depends in which host enviroment you want to use JavaScript.
If inside a browser (where speaking of ECMAScript might be more
suitable), you should get accustomed to the developer tools of the
browser(s) first, see <http://devtoolsecret....

Hi Phil,

The Firebug add-on for Firefox has rudimentary but adequate tools for basic debugging if you are developing for the browser, I use it daily and it always meets my needs.

ECMAScript _implementation*s*_. (I know that you probably know this: )

It is vital to understand (which is why I do not tire to point it out) that
there is not only one such scripting language as ECMAScript implementations
differ from one another. For example, you will already find some features
of ECMAScript Ed. 6/2015 in Mozilla JavaScript, but not yet in Google V8
JavaScript (the more Canary, the more likely that you find them there, too).

If you write your code only based on superficial reading of MDN (neglecting
the top or bottom section of articles), and test it only in Firefox or
Seamonkey because you are thinking â??JavaScriptâ?, it can *break* in
Chromium/Chrome even if it is syntactically correct (or *considered*
syntactically correct by Firefoxâ??s script engine; there are also syntax
extensions in implementations, in *full compliance* with the Specification
text). And those are only two implementations and two runtime environments
of much more.

Which is referred to in the â??FAQ for comp.lang.javascriptâ? (see below),
thanks to you :)

Thanks Matt, Christoph & Thomas - yes, I am thinking of browser-based
implementations (and my heart sinks at the compatibility differences!).

Is there anything more specialised in common use - anything like Visual
Studio, for example? I did fool around today with Chrome's developer
tools, and they've come on a lot since I last saw them. I'll need to
read a manual even!
