What is $ ?
- In jQuery, $ is an alias for jQuery. From the above statement we can able to understand, function are available without using $.
- If you need to use another JavaScript library along side with jQuery, then it will return control of $ back to the other library with a call to $.noConflict().
- if noConflict() is used than the references will be restored.
Is possible to change $ symbol?
Yes, we can use any alias name instead of $, by changing the below line
// Expose jQuery to the global object
window.jQuery = window.$ = jQuery;
where jQuery on the right side is the function-scoped reference.
This will be available in jquery plugin. if u want to change it to JQ then we want to change like below
// Expose jQuery to the global object
window.jQuery = window.JQ = jQuery;
after library loaded in your application you can use JQ instead of $.
