XML vs JSON
| JSON | XML | |
|---|---|---|
| Human Readable | It's easy to read because it's just defining objects and values. | Less readable because it's contained within markup tags |
| Compact Code | Less code than XML | More code than JSON |
| Speed of Parsing | Quicker, because it's defined as object and value | Slower, because the data has to be extracted from tags |
| Ease of Creation | Easier, because syntax is easier | More like programming so more knowledge is needed. |
| Flexibility & Extendibilty | Only works with limited data types, not enough for all applications | Gives total freedom, because you can create what data types there are, so it has greater flexibility |
