JSON VS JSONP

Hello everyone, I've been kind of confused about these two and what their differences are and when to use either one. If anyone could give me a quick explanation I'd appreciate it thanks!

Cesar;

JSONP is basically a workaround that bypasses cross domain scripting policies. Instead of making an AJAX call and requesting JSON, you actually create a script tag, with the get call as the SRC attributes of the script tag, which is allowed to call across domains, the difference is, instead of JSON, you get JSON wrapped in a function call, so when the script tag completes, it runs the call which basically is passing the JSON you wanted in the first place.
