Overview of this book

If you're writing applications that move structured data from one place to another, this book is for you. This is especially true if you've been using XML to do the job because it's entirely possible that you could do much of the same work with less code and less data overhead in JSON. While the book's chapters make some distinction between the client and server sides of an application, it doesn't matter if you're a frontend, backend, or full-stack developer. The principles behind using JSON apply to both the client and the server, and in fact, developers who understand both sides of the equation generally craft the best applications.

There's more…

Once you run this command to install the compiler, you'll have the TypeScript compiler tsc available on the command line. Compiling a file with tsc is as easy as writing the source code and saving in a file that ends in .ts extension, and running tsc on it. For example, given the following TypeScript saved in the file hello.ts...
