avoid nested if in javascript

Question

I need to check if auth.runtime.status is equal 200, but something the auth.runtime is undifend, is there more elegant way to do it in nodejs

    if (auth.runtime) {
            if (auth.runtime.status == 200 && auth.application.status == 200) 



...

 }
}

is there a better way to write it?

lets assume I've more nested if

you need to add else condition on your question and then we can help you — sumit, Jun 08 '20 at 11:02
Show as much as possible, i.e. what should happen if `auth.runtime` is `undefined` — goto, Jun 08 '20 at 11:03

You could take the optional chaining operator ?. with a single if statement.

if (auth.runtime?.status == 200 && auth.application.status == 200)

This assumes `optional chaining operator` is supported by whatever environment the OP is using, and is currently not supported in `Node.js`. – goto Jun 08 '20 at 11:24
