"JavaScript Fatigure" is real. In the last 5 years JS has moved from being something used to progressively enhance a web page, to being the driving engine that powers entire web apps. And as we try to do more with JavaScript, we need more tooling. Webpack, Babel, CSS Modules and type checking. And we needed more frameworks: we went from jQuery everywhere to Backbone, Angular, React and Redux and MobX and Preact and more. It some point, it got really, really complex, hard to get started, easy to break, and less fun to build.

Dapp is the new approach to combine the power of blockchain and modern cryptography into the web application. In this session, we will demo how to build a simple web application using web3 and MetaMask, and manipulate the Ethereum chain with it.

The development experience of desktop and web application is different, but their gap is getting closer. A modern JavaScript application also needs a build script for “compilation" for deployment like a desktop application.
