Document Object Model or DOM in Javascript is an interface that allows developers to change the content, appearance, and structure of a website.
The basic structure of a website is composed of static HTML and CSS code. In order for the website to appear more dynamic, the Javascript programming language is needed. Dynamic JavaScript differs from static HTML and CSS which make them unable to communicate with each other.
As a result, the DOM was created as a link to connect Javascript with HTML and CSS. The role of the DOM is to allow Javascript to access and modify all static elements on a web page.
DOM in Javascript is very important to use in making a website. As explained earlier, Javascript can not understand HTML documents directly. Therefore, DOM plays a role in representing the same HTML document but with different formats using objects.
As an example, Javascript can not understand the <h1>H1</h1> tag format in HTML files, but it can understand H1 objects in the DOM.
After understanding what DOM is and the importance of using DOM in creating a website, then you also need to know what DOM properties are.
The properties in the DOM are used to access and modify HTML documents. To give you a better understanding, here are the properties in the DOM:
The way DOM in Javascript works is by manipulating web pages so that they are more dynamic by retrieving, changing, adding, or removing HTML elements. In addition to performing manipulation, DOM can also collect data, functions, and attributes belonging to the elements that are accessed.
