What are the distinctions in between Firefox's Javascript engine and also Chrome's V8?

I've seen that Chrome and also Firefox take various quantities of time to provide particular points. As a whole, Chrome has actually been much faster. What need to I find out about both of them (and also IE8/9, also, I presume) when creating a Javascript/jQuery application?

If you write a jQuery application , you do not require to bother with anything as you are creating to a framework/library that does (today) and also will certainly remain to do (in future variations) every little thing under the hood.

if you are writting simple javascript , after that it's all a mess :)

as you need not to create your application in one internet browser yet to examine in all various other browsers, and also simples points as opening up home windows and also take care of ajax telephone calls differ from engine to engine ...

so ... please maintain intending to jQuery :) he will certainly do the liquor for you ;)

Actually, Spidermonkey (FF) and also V8 (Chrome) are really comparable in the core javascript engine API because both attempt to be criteria certified. The major distinction is that Spidermonkey often tends to add some wonderful bonus to their API if they feel it is required. Every one of this is located at the Mozilla Development Center (MDC) for JavaScript and also well recorded if it is not a criterion. On a side note, I directly search the MDC as my key resource for the JavaScript API.

This tale is totally various for IE. While a lot of the core API such as Math and also String coincide, IE varies substantially when it involves the document object, and also any kind of adjustment therein I would certainly concur with balexandre and also claim that jQuery does a great work at caring for that mess for you.

The last point that I will certainly state is while each engine will certainly refine the JavaScript code in different ways (some much faster, some slower, etc), yet this can primarily be taken into consideration a black box and also all you need to require to bother with are the distinctions in the APIs.
