JavaScript for Automation (JXA) Resources

JXA Resources

Revised: 2019-11-28 16:16 GMT-6

JXA

This is a list of the key resources I have found useful. If you know of others, please post in a comment below, and I will add to this list.

I have tried to order this list in the order that, to me, is best for learning JXA from scratch. We all learn a bit diferently, so adjust to suit your style/needs. Please post if you have suggestions on learning JXA.

export const Example = ({ loadOnlyOnce }) => {
    useEffect(() => {
      loadOnlyOnce()
    }, [loadOnlyOnce]) // ← WHY？
}
