| - Added the `startswith(value, prefix)` function extension. `startswith` returns `True` if both arguments are strings and the second argument is a prefix of the first argument. See the [filter functions](https://jg-rp.github.io/python-jsonpath/functions/#startswith) documentation. |

This can be implemented with regex, so this is for performance?

Hi @He-Pin,
I have a use case where operators like and and or are preferable over && and ||, for example. Adding functions like startswith() where match() would do fits in well in that particular scenario.
Maybe non-standard function extension should be disabled in the new "strict" JSONPath environment 🤔

we have something like this too, like isChiness to filter out Chinese text when we do TaoBao English.
Thanks for sharing
