+
+The **`.setAttribute()`** method of the Element interface sets or updates an attribute on the specified element. If the attribute already exists, its value is updated; otherwise, a new attribute is created with the given name and value.
+
+## Syntax
+
+```pseudo
+setAttribute(name, value);
+```
+
+- `name` (string): The name of the attribute to set (e.g., `"class"`, `"id"`, `"href"`).
+- `value` (string): The value to assign to the specified attribute.
+
+## Example
+
+This example sets the `name` attribute of a button element to `"helloButton"`:
+
+```js
+const button = document.querySelector("button");
+
+button.setAttribute("name","helloButton");
+```
