Why would a jQuery variable start with a dollar sign?

jQueryWeb DevelopmentFront End Technology

When you will begin working about jQuery, you will get to know about the usage of the $ sign. A $ sign is used to define jQuery.

jQuery variables begin with $ to distinguish them from a standard JavaScript object. Also, it is a convention. jQuery selectors start with the dollar sign and parentheses() − $.

Let's take an Example

// jQuery object
var $phone = $("#myphone");
// dom object
var phone_el = $("#myphone").get(1);
