Frequently Asked Questions
DOM stands for Document Object Model, which is a programming interface for web documents. It represents the HTML or XML document as a tree-like structure where each node in the tree represents an element, attribute, or piece of text in the document.
There are several ways to select HTML elements using the DOM. Here are some of the most common methods:
getElementsByTagName(), querySelector(), querySelectorAll(), getElementsByClassName(), getElementById()
getElementsByTagName(), querySelector(), querySelectorAll(), getElementsByClassName(), getElementById()
Event bubbling is a process that occurs when an event is triggered on a particular element in the DOM hierarchy and then propagates or bubbles up through the parent elements until it reaches the top level or the root of the document.
A callback function is a function that is passed as an argument to another function, and is executed by that function when a certain condition or event occurs. Callback functions are often used in asynchronous programming to handle tasks that take time to complete, such as making a server request or waiting for user input.
