Semicolon replaced by comma when using dollar sign (jquery)

[charlesbdudley]

Original Code:

$( 'body' ).css('background','red');
$( 'div' ).css('background','blue');

Uglified Code:

$(\"body\").css(\"background\",\"red\"),$(\"div\").css(\"background\",\"blue\");

Notice the comma added before $(\"div\")

Using commas to separate statements instead of semicolons is valid ECMAScript, even though some implementations do have issues with it. Check out http://my.opera.com/hallvors/blog/2012/07/17/twitter-crashes-itself-with-commas.

Ah, thanks @lautis. Setting :seqs => false gets around this.

Uglifier.new(:seqs => false).compile(File.read("app/assets/javascripts/temp3.js"))
=> "$(\"body\").css(\"background\",\"red\");$(\"div\").css(\"background\",\"blue\");"
