What is hast-util-is-element?

It provides functions to check if a node is an element and optionally matches a given tag name. This is particularly useful when manipulating or inspecting HTML represented within JavaScript.

What are hast-util-is-element's main functionalities?

Check if a node is an element

This feature allows you to verify if a given node is an element node within a HAST structure. It's useful for filtering or processing nodes in a tree.

const isElement = require('hast-util-is-element');

const node = {type: 'element', tagName: 'div'};
console.log(isElement(node)); // Outputs: true

Check if a node is a specific element

This feature extends the basic check to allow for specification of the tag name. It's useful for finding or working with specific types of elements in a document.
