I have times in my JS code where a function may be undefined, and I want to call it only if it's defined. I write function && function(). Is there a more concise way to do this? Something like function.callIfExists()?

2You can use the optional chaining for this. `function?.()` – GmBodhi May 29 '23 at 15:42

2Ask yourself why a function may be undefined and rather fix that? Sounds like an unsound program structure. – deceze May 29 '23 at 15:43

What if it's a function param, which maybe exposed to the client? @deceze – GmBodhi May 29 '23 at 15:46
