The selector thing is a query language, and very powerful / abusable. Pretty much like SQL or any other 4th generation programming language. Is high level, so you always have the risk of people doing something weird, but normally allow for JQuery programs to do in 3 lines of code what normally will take 30 or 50 lines. These 3 lines have less probability to be bug free, and shows intention better than the low level enhanced javascript code. The Javascript language is hard in a non obvious way, and this help is necessary. -- -- ℱin del ℳensaje. _______________________________________________ Wikitech-l mailing list Wikitech-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l
