The sequence of operations when assigning in Typescript with || and utilizing the array .find method

I need to ensure that the operations in my assignment are happening in a specific sequence. As far as I can tell, it should be following the order listed below. However, I have not been able to locate any documentation on TypeScript that definitively confirms or denies this.

const currentFreak =
this.allFreaks.find(freak => freak.id === currentFreakId) ||
this.allFreaks.find(freak => freak.Active) ||
this.allFreaks.find(freak => freak.defaultFreakId);

Can I assume that the above code is being executed in order using short-circuit logic? I found some information on this topic in the TypeScript documentation at this link, but it seems unclear based on my interpretation of it.

Answer №1

The behavior of this code is similar to JavaScript, meaning it does follow short circuit logic. If there is a freak with the same ID as the currentFreakId, the second .find method will not be executed.
