Delving deeper into JXA

Delving deeper into JXA

Although JXA is quite capable, there are some things that are difficult or impossible to achieve with it alone. For example, printing only certain pages of a PDF document via a script or extracting all images from an HTML document is not easily feasible with a script.

Whenever JXA falls short, you can try to find an alternative solution by calling out to the frameworks included with macOS. Apple provides an ObjC-JXA-bridge for that: From your JXA script, you can call ObjC methods and use their return values.

This is described further in Marrying JXA with ObjC.
