jQuery.noConflict() function

The jQuery remove the conflicts the global function and to define variables using jQuery.noConflict().

For example, If you used the jQuery and other tools both are using use $() as their global function and to define variables. In that situations conflicts the  global function and define variables. The using jQuery.noConflict() function we avoid  or remove the client side libraries conflicts. we can create custom specific character in the place of $ sign in jQuery.

The example in detail as given below.

jQuery.noConflict();
// Use jQuery via jQuery(...)

$(document).ready(function () {
    $("div").hide();
});
OR

jQuery (document).ready(function () {
    jQuery ("div").hide();
});

OR

$(function () {
    $("div").hide();
});

We can use and create your custom specific character in the place of $ sign in jQuery. i.e.

var $jQ = jQuery.noConflict();
// Use jQuery via jQuery(...)

$jQ(document).ready(function () {
    $jQ("div").hide();
});
OR

$jQ(function () {
    $jQ("div").hide();
});
