 The `view` argument is a string that is the file path of the view file to render. This can be an absolute path, or a path relative to the `views` setting. If the path does not contain a file extension, then the `view engine` setting determines the file extension. If the path does contain a file extension, then Express will load the module for the specified template engine (via `require()`) and render it using the loaded module's `__express` function.
