Hi Fergus,


Thanks for your clarification.  My wording could have been better.


According to the Web page "The TIOBE Programming Community index is an
indicator of the popularity of programming languages."  There is probably a
correlation between searches for a programming language and knowledge or
desired knowledge of a programming language.  Of course, programmers can
know (or want to know) more than one programming language.


No matter how you look at it, the 2% number for JavaScript relative the
other languages seems low.  However, as previously discussed, it might be
more informative to know the percentage of developers who know HTML relative
to JavaScript (non-mutually exclusive).  It would be constructive to find
numbers related to this.


Best regards,

Hi Everyone,

I mentioned some numbers from an article that I noticed last week:
http://www.tiobe.com/index.php/content/paperinfo/tpci/index.html.  The top 2
programming languages are known by about 17% of the programmers (each).


That is not what the 17% number on the web page that you cite means.


The Tiobe index
doesn't track what proportion of programmers know each language.

It essentially just tracks the number of web search hits for "<foo>
programming" for each language <foo>,

and normalizes this so that the top 50 languages account for 100%.

That's a completely different measure.


Many programmers -- and all the good ones -- know more than one programming


JavaScript is known by about 2% of programmers.  This might be surprising


Or it might be just plain wrong.


given the billions of Web pages out there.

Having a JavaScript API is fine, but keep in mind that there are many HTML
developers who know little to no JavaScript.  It's good to have a
declarative markup option for those who specialize in markup.  The
JavaScript API should then fit with and extend the declarative markup
option.   That's easier to do now than to retrofit later.

Best regards,
