Bubbling in real life is when a bubble goes from the bottom of the glass to the top of it. When you put the soda into the glass, you see bubbles go from the bottom to the top. But in the JavaScript Programming language, Event Bubbling happens when you have an event on an element of a web page. The execution of that event starts from the lowest element to the top element. So event bubbling is the process of executing the document object model events starting from the element where we add that event until we reach the top parent element.

Who invented JavaScript, how it works, as we have given information about Programming language in our previous article ( What is PHP ), but today we will talk about what is JavaScript, why JavaScript is used The Answers to all such questions and much other information about JavaScript, you are going to get here today. Hope this information will work for you.
JavaScript language was invented by Brendan Eich in 1995. JavaScript is inspired by Java Programming Language. The first name of JavaScript was Mocha which was named by Marc Andreessen, Marc Andreessen is the founder of Netscape and in the same year Mocha was renamed LiveScript, and later in December 1995, it was renamed JavaScript which is still in trend.
JavaScript is a client-side scripting language used with HTML (Hypertext Markup Language). JavaScript is an Interpreted / Oriented language called JS in programming language JavaScript code can be run on any normal web browser. To run the code of JavaScript, we have to enable JavaScript of Web Browser. But some web browsers already have JavaScript enabled.
Today almost all websites are using it as web technology, mind is that there is maximum scope in JavaScript in the coming time, so if you want to become a programmer, then you can be very beneficial to learn JavaScript.
In JavaScript, ‘document.write‘ is used to represent a string on a browser.
<script type="text/javascript">
document.write("Hello World!");
</script>
<script type="text/javascript">
//single line comment
/* document.write("Hello"); */
</script>

To be clear, even bubbling and event capturing is not a react concept but a javascript & concept surrounding the behavior of the dom.
To understand event bubbling, we first need to understand how the dom works.
DOM, also known as Document Object Model, is the data representation of all the nodes and contents of the web application.
This probably doesn’t make a lot of sense unless you are a developer so allow me to be even more bare bone about this:
Here is a better picture of how it can look like:
Let’s say we the div and the p are attached with onClick functions themselves, with the div’s onclick function printing out “console.log(“this is div”)” and the p’s onclick function printing out “console.log(“this is p”)”.
With event bubbling, when the user clicks on p it will bubble down to p, trigger the onclick function there, the trigger div’s onclick function and another onclick function that its parents and/or grandparent nodes contain.
The workflow will be as following: p->div-> body-> html
Here is an example of how it will work in a react application:
