Mikeal, So, the Math object is "no good"?

I have to admit that the few times I've seen people using First letter casing for non-constructors I've immediately decided that their code is no good, which is probably a little reactionary on my part. Crockford puts it well: "Constructor functions which must be used with the new prefix should start with a capital letter. JavaScript issues neither a compile-time warning nor a run-time warning if a required new is omitted. Bad things can happen if new is not used, so the capitalization convention is the only defense we have." -Mikeal PS. I've now more or less settled on Isaac's style guide which is used by npm https://github.com/isaacs/npm/blob/master/doc/coding-style.md although I do use semicolons on new lines after large var declarations because I find that newer developers think the statement ends ambiguously.

I'm actually aware of and have studied quite thoroughly both of the resources that were provided - I'm kind of a "stickler" for style guides. I was actually very specifically looking for an answer regarding First letter casing for non-constructor built-in objects, ie. Math and Proxy. I think the legacy Java style guide influence addresses the question as best as I can hope for.

The Google style guide also isn't too bad http://google-styleguide.googlecode.com/svn/trunk/javascriptguide.xmlcript.crockford.com/code.html , though I disagree with /wrong button On Fri, Sep 9, 2011 at 9:00 PM, Dmitry Soshnikov <[email protected]> wrote: > Also, style guides with 2 spaces indention are also good and wide-spread > (other things are the same as described in the link which Mark gave -- this > is Java's style guide by the way). > > On 09.09.2011 22:10, Mark S.
