I couldn’t agree more with the leading commas. I actually started this a long time ago with my SQL scripts. I did this for similar reasons: it was a lot easier to comment out lines (fields) if the comma preceded the statement and still have the script run. In my opinion this should be the standard for coding or at least a recognized option. Also, thanks for helping out us noobs!

Two more points in support:
* diff in case of leading point will give only one line difference;
* using an IDE when one comment a single line (in case of commenting last line of csv-like block of code) there\’s no worry about fixing one extra comma issue from previous line.

I always use trailing comma’s… indeed, now i read your article it seem plausible to use leading comma’s.

Still, i just don’t like the sight of it, and i like to see my code in beauty

I have been using ExtJs for a couple months now, using editor as simple as VIM. Being bitten by the IE issues, also cases where I would append additional line at the end for declaration and forget to add a comma at the end of previous line, and keep wandering about wierd errors…
Couldn\\\’t make my mind to change the coding style proven by years and move my code to use leading commas.. Until this point.
Thanks for your post Saki, it finally made up my mind.

I use spket plugin for Eclipse when coding and it’s validation throws a warning for extra commas. I find that trailing commas are more pleasant to read, so I think this is very workable.

Thanks Saki for all of this excellent content.

@nesha,

thank you for your comment. Nevertheless, I won’t change my coding style.

I think that if several people should inspect your code, work on it and reuse it, it is better to keep up with common practice which is, trailing commas. IE glitch (so as many other syntax error) can be fixed by using appropriate tools/editors. Eclipse with Spket plugin and ExtJS support added to it works like a charm. Not only that it marks syntax errors, but it allow code completions, better code colors… It made life of all in my team soooo easier.

Initially I was confused by the leading comma – now i am a big fan.
Thanks for showing us this.

I only wish I could get Aptana’s sh-ctrl-F reformatter to not undo all my hard work

Good point. I had never tried that JSLint option. It solves the issue. Thanks!
