I have no idea about <i>leading</i>, but the two JS-specific places I go are:<p><a href="https:&#x2F;&#x2F;www.reddit.com&#x2F;r&#x2F;javascript" rel="nofollow">https:&#x2F;&#x2F;www.reddit.com&#x2F;r&#x2F;javascript</a><p><a href="http:&#x2F;&#x2F;www.echojs.com&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.echojs.com&#x2F;</a><p>Edit to add the esdiscuss mailing list if you want talk about the language itself, although it has been dying a slow death in recent months as the authoritative voices of old seem to avoid it now:<p><a href="https:&#x2F;&#x2F;mail.mozilla.org&#x2F;listinfo&#x2F;es-discuss" rel="nofollow">https:&#x2F;&#x2F;mail.mozilla.org&#x2F;listinfo&#x2F;es-discuss</a>
