It takes a JavaScript script as an argument, which must provide a function called `Process`. The JavaScript `Process` function can be used to, for example, collect information such as how many hits each page served by the fictional web server gets. -### [`shell.cc`](https://github.com/v8/v8/blob/master/samples/shell.cc) +### [`shell.cc`](https://github.com/v8/v8/blob/main/samples/shell.cc) This sample takes filenames as arguments then reads and executes their contents. Includes a command prompt at which you can enter JavaScript code snippets which are then executed. In this sample additional functions like `print` are also added to JavaScript through the use of object and function templates.
