-Tabris.js 3 targets TypeScript 3.8. TypeScript is a <em>type-safe</em> dialect of JavaScript/EcmaScript and also supports <em>ES6 module syntax</em> (`import` and `export` statements) and `async`/`await`. A complete guide to TypeScript can be found at [typescriptlang.org](http://www.typescriptlang.org/docs/home.html). As an IDE we can recommend [Visual Studio Code](https://code.visualstudio.com/) with the [eslint](https://marketplace.visualstudio.com/items?itemName=dbaeumer.vscode-eslint) extension, but there are [many suitable TypeScript IDEs](https://github.com/Microsoft/TypeScript/wiki/TypeScript-Editor-Support) out there.
