Do they do the same thing ?
Which one should I use inside client?
if ( Meteor.is_client ) { Meteor.startup(function () { // my code here
I just ran into an issue that $ was called before template rendering so I hade to use Meteor.startup
$
So I'd say that if you need to work with DOM elements you have to use Meteor.startup (I used it for the jQuery File Upload plugin)
Meteor.startup
