In fact, it is not uncommon to hear web professionals cite that
“Flash is dead,” but despite suddenly becoming the underdog,
Flash still has some advantages if used the right way:
y Because it uses vector graphics, Flash files are small and can
be resized without loss of detail.
y It is a streaming format, so movies start playing quickly and
continue to play as they download.
y You can use ActionScript to add behaviors and advanced
interactivity, allowing Flash to be used as the frontend for
dynamically generated content or ecommerce functions.
y The Flash plug-in is well-distributed on PCs, so support on
desktop browsers is reliable.
y Although HTML5 is promising and rapidly evolving, as of this
writing, it cannot match the features and performance of
Flash.
Flash is not likely to disappear overnight, but even Adobe is
putting its muscle behind HTML5 alternatives.
