Need to resolve conflict to Multiple jQuery's from single page

[dmuralimohan]

I have initialized window.jQuery = jQuery; now, i want to add some prototype functions with different jQueries, like
var a = window.jQuery;
var b = window.jQuery;
a.fn.helloWorld = () => 1;
b.fn.helloWorld = () => 2;

console.log(a.fn.helloWorld()); // 2
console.log(a.fn.helloWorld()); // 2

In this case, when i use noConflict from a variable, then b has undefined then, how can i use jquery for this case?
