Frameworks will never be as fast as Vanilla JavaScript

Frameworks will never be as fast as Vanilla JavaScript

Can JavaScript frameworks ever be as fast as vanilla JS web apps? The answer is no. The reason for this and why it is not bad at all — this article will give you the answers.

Frameworks and libraries like React.js, Vue, and Angular are actually a fixed part of the knowledge of every web developer. Before starting a new project, there is often no longer the question of which framework to use. Whether to use Angular, Vue, or React.js is often a matter of taste. Then you only have to decide which additional tools and which backend should be used.

A look at platforms that show you how to use JS frameworks confirms this — most of the world’s most important websites are built on complex frameworks and libraries.

Not even with server-side-rendering…

…can JavaScript frameworks be as fast as Vanilla-JS.

Server-side-rendering vs. client-side-rendering is a discussion that clearly favors one side. In most cases, server-side-rendering, or static pages that do not need to be rendered by JavaScript, is superior.

Why this is so is easily explained.

Server-side-rendering (rendered) / static: Page with finished HTML structure is sent to the client browser. The client browser knows directly through the HTML structure what it should display.

Client-side-rendering: The server sends an HTML template to the client browser, which does not yet have a finished structure. The HTML template is read and processed, it requests one or more large JavaScript files. These are also sent. When processing the JavaScript, the HTML structure of the page is built up. Only then the browser can visually display what it is supposed to display.
