catching runtime error

use Eval to run the code, and check the result. I do this on some high risk code. Used occasionally and with caution, it can be handy. Other than that, use rodash, or similar library for getting chained objects e.g. a.b.c.value

Thanks George. I am thinking of using Eval to do all my risky operations. Sounds like a reasonable approach. I avoid using chained values. I usually get my data bound to interfaces and have listeners on them to catch them into a local data. That way with a single rendezvous I can propagate variable repo to all files with minimum access to global node. Rodash library looks great. I will dive deeper and have a look at it.

glad it worked out. Yeah, I'm not fan of chained access - I have a pattern whereby I do all that in my takss; but even then, I can never be sure I got the json right from the server, so I use rodash.get() to avoid crashes in those circumstances. don't over use/abuse eval!! There are smarter people here than me, who can tell you why.

That's right. I have seen some other posts where devs have mentioned it. Somehow I feel it was easy to use in the SDK1. But I don't know any better. I never worked on SDK1.
