I've written a cheat sheet for Javascript with active links toMDN pages


(Developer Documentation Graveyard :: JavaScript, enhancement, P5)



(Not tracked)



(Reporter: author, Assigned: cmills)


(Whiteboard: [specification][type:feature])

What problem would this feature solve?
Is it .slice() or .splice()?  For anyone accessing the API they need a quick-reference.   This might mean 
(1) instant 'ah yes - that's the method I want' just from the name.
(2) Of course!  It returns -1 not undefined, from the headline, or
(3) let's check the details by going to the method page.

With an up-to-date quick reference, programmers can access the full scope of Javascript features.   Without it they may be relying on partial or obsolete hard-coded references or even memory.

Who has this problem?
All visitors to MDN

How do you know that the users identified above have this problem?
I use it every day.

How are the users identified above solving this problem now?
The hard way.  Or not using the full scope of Javascript.

Do you have any suggestions for solving the problem? Please explain in detail.
I've written just such a thing, which is a simple automated scrape of existing API pages.  It's available at in a standalone, downloadable or instantly usable form.

Perhaps this useful tool would be re-skinned and re-homed for the MDN pages.

* Complete with the scraping code.
* Caches the result in localStorage after first scrape.  (ie If it detects no local pretty HTML ready to show it will create it.)
* Tool-tip (actually just TITLE attribute) is the headline
* Button link goes straight to API method/property page on MDN
* Array,String,Date,Math,Object,Number,Promise,RegExp

Is there anything else we should know?
Please drop me a line if you're *NOT* interested. 
It's all free of course.
