In Detail

Web applications work on a range of different devices, making them one of the most common ways in which users experience the web today. However, while the flexibility of web apps are great for users, for developers creating them with JavaScript, the process can be difficult, requiring more extensive and detailed coding work. TypeScript helps make the development of web apps easier, allowing you to quickly create scalable applications that will reach desktops, tablets, and mobiles. With TypeScript, your code becomes much more manageable and your work much more efficient. Its additional features, such as static typing, facilitate IDE support and further tooling.

This quick and insightful guide will provide you with an easy way into TypeScript. You will discover the features of the TypeScript language and gain hands-on experience in creating a web application with reusable components. You will explore the compiler and learn how to manipulate the resulting output to fit specific needs.
