### `js_new()`
This function is a convenience function for calling JavaScript's `new`.
The first argument is the name of the class, the following arguments are
passed to the constructor. It returns the same thing as the `js()` function,
in this case that would be the new object. For example:
js_new('Blob', ["<html></html>"], {type=>"text/html;charset=utf-8"})
is the same as calling this in JavaScript:
new Blob(["<html></html>"], {type:"text/html;charset=utf-8"})
This function was added in WebPerl `v0.05-beta`.
