Creating a Frontend Framework from Scratch

We use frontend frameworks every day, but we hardly really understand what happens under the hood. Creating our own framework is a great way to learn how it works with the DOM, generates page views, passes data between components, and interacts with the operating system. Step by step, we will create our own framework in JavaScript and publish it as an npm package.

It's time to understand how a modern framework works, learn to manage component states and their lifecycle, work with the virtual DOM, and use reconciliation algorithms for efficient HTML updates. All key concepts are presented in simple language and accompanied by diagrams. Many concepts are borrowed from React, Svelte, Angular, and other well-known tools
