What are the differences between JSON and JSONP?

Question

Format wise, file type wise and practical use wise?

Answer 1

“JSONP is JSON with extra code” would be too easy for the real world. No, you gotta have little discrepancies. What’s the fun in programming if everything just works?

Turns out JSON is not a subset of JavaScript. If all you do is take a JSON object and wrap it in a function call, one day you will be bitten by strange syntax errors, like I was today.
