What is Document Object Model (DOM)?
This article sheds light on the Document Object Model (DOM), a critical concept in web development that defines the logical structure of documents and the way a document is accessed and manipulated. With the DOM, programmers can build documents, navigate their structure, and add, modify, or delete elements and content. The DOM represents the document as a tree structure where each node is an object representing a part of the document. The article explores how the DOM is not part of the JavaScript language, but rather a web standard that can be used with any programming language. It delves into how manipulating the DOM with JavaScript allows for dynamic content change - making web pages interactive and responsive without needing to reload the page. It discusses best practices for efficient DOM manipulation, common pitfalls, and performance considerations to keep in mind to ensure web applications run smoothly. Moreover, it highlights how LoadFocus tools can help developers measure the impact of DOM manipulations on the performance of web applications, ensuring an optimal user experience.
