DOM is the abbreviation of Document Object Model, which can be said to be a model structure. Javascript is a client-side scripting language (although it can also be used as a server-side scripting language, it is rarely used in this way, so it is still counted as a client-side scripting language).

Javascript mainly uses HTML DOM to obtain, change, and create HTML elements, so as to achieve the goal of beautifying the page and operating the page elements. Therefore, the most common ones in Javascript are various HTML DOM elements and their respective attributes. In addition to these DOM elements, Javascript has its own objects, such as arrays.
