As Web apps are highly interactive, users do not want to wait for a full page reload every time an action is performed. That's why JavaScript is used to update the HTML directly using the DOM, to provide a smoother user experience.

 Another approach is to have only one HTML file, and define multiple [HTML templates](https://developer.mozilla.org/docs/Web/HTML/Element/template) using the `<template>` element.
