how to remove the list of values from json object to another json object using jquery

for example I have two JSON Object. One of them is var A={'Header','Quotes','Returns','indent','Basic'.....,'Placing'.} another Object having Var B={Header','Quotes','Returns','indent'....}

in B having some Header,Quotes,Returns and Indent. So if A having same elements need to remove in jquery.

A's Final Output should be A={'Basic','Placing'.....}
