Confused by Javascripts
<p>Decided it's about time to learn Javascript.  On initial investigation a few questions have raised in my mind such as:  Are there many Javascripts?  If so what do I need to watch out for?  How much do Javascripts differ from ECMAscript (or from each other) and which Javascripts are up to date with the latest ECMAscript?  What is the low down on Javascript, if the above questions are true, is there a core/standard that I should concentrate on?</p>

<p>Hope this doesn't fall into the vague or not appropriate category it's just that Javascript "seems" to me to have a lot of...inconsistencies?...gotchas even..?</p>

<p>Am I right?  I am sure there are many differing opinions but I feel I might need to thread my way through until I get an answer to these questions.</p>

<p>Many thanks for looking and apologies if this is not a suitable question for this forum.</p>

<p>Regards</p>

<p>Thanks, Ian</p>
