Javascript - Attach functions to array of elements returned by a selector

elements.js

const $ = function(selector) {
	return new $.elements(Array.from(document.querySelectorAll(selector)));
}
$.elements = function(elements) {
	this.html = function(text) {
		elements.map((element) => element.innerHTML = text);
	};
	this.load = async function(filePath) {
		this.html(await (await fetch(filePath)).text());
	};
	return this;
};

// $('title').html("Title changed"); //Sets the innerHTML of the html title element using the tag name
// $('p').html("This is a paragraph"); //Sets all innerHTML of all html p elements using the tag name
// $('#app').load("path/to/file.html"); //Sets the innerHTML of an element with id of 'app' to the contents of a file
