In order to resolve the conflict between Jquery & any other JavaScript framework that also use the '$' sign as a shortcut the jQuery team implemented a method called the noConflict() method.

    What this method does is that,it releases the hold on the '$' shortcut identifier. But we can still use jQuery keyword for writing our query instead of the '$' sign.

Example:

$.noConflict();
jQuery(document).ready(function(){
    jQuery("button").click(function(){
        jQuery("p").text("jQuery is still working!");
    });
}); 

    We can also create our custom keyword instead of jQuery keyword, as noConflict() returns the reference of jQuery which we can store in any object.

Example:

var jq = $.noConflict();
jq(document).ready(function(){
    jq("button").click(function(){
        jq("p").text("jQuery is still working!");
    });
});
