What’s the difference between an “attribute” and a “property”?
Attributes vs. Properties in HTML and JavaScript
In the realm of web development, understanding the distinction between attributes and properties is crucial for manipulating the Document Object Model (DOM) effectively. Despite their apparent similarities, attributes and properties serve different purposes and behave in distinct ways. The HTML attribute vs DOM property distinction matters most for form inputs; see MDN’s HTML attribute reference.
Attributes: Defining Initial Characteristics
Attributes are defined directly in HTML and provide initial configuration and settings for elements. They are key-value pairs present in HTML tags that define characteristics such as id, class, or value. Attributes represent the state of an element at the time the page loaded.
<input type="text" value="Initial Value">Properties: Reflecting the Current State
Properties, on the other hand, are part of the DOM’s JavaScript representation of HTML elements. They can change as a result of user interaction or programmatic actions. While attributes offer a snapshot of an element’s initial state, properties reflect its current state.

console.log(document.getElementById('myInput').value); // "User Input"Interplay Between Attributes and Properties
