Flash vs Javascript [closed]

Question

Update 2:

To add swf in web page Swf Object 2.0 is most used method, which is a javascript library, so flash will be depend on availability of JavaScript.

So if javascript disabled then flash will not play.

I always heard approx 5% users in the world keep JavaScript turned off.

But Adobe claims

Flash content reaches 99% of Internet viewers

Is it true even iphone, ipad and blackberry doesn't support Flash?

if it's true then if same thing we can achieve with FLASH and JavaScript , then should we go for flash (If we are not considering iphone, ipad and blackberry)?

And if we also need support on iphone, ipad and blackberry for our website/web applications, then should we never use flash?

Update:

Firefox's plugin

Noscript has downloaded 67,446,249 times till date

but Flashblock only 8,723,436 times

Is it means people dislike JavaScript more than Flash?

Answer 1

A few things to consider:

These days, users who disable JavaScript usually do so with a tool like NoScript, which also disables Flash. That means you probably would't reach any more users by developing in Flash.

There are many new users browsing with mobile devices every day, and as you pointed out, some of the most popular ones don't support Flash at all. Even those that support Flash often don't run it very well. On the other hand, nearly all web-enabled devices are now being made with optimized JavaScript support.

Unlike Flash, JavaScript is not controlled by a single company. That means many more people are working to improve its performance, reliability, and features. Your users will benefit from this in the long run.

If you are able, JavaScript instead of Flash.
