I have this code in javascript:
val: a ? a : ''
Basically checking that a is not null before assinging it.
The problem is that a is double in the line.
Is there a shorter way to do this like:
val: a ? ''
? Thanks

How about `a ?? ""`? The semantics are different though: `a ? a : ""` isn't checking if `a` is not null, it's checking if `a` is falsey which happens to include null. `a ?? ""` is also checking undefined in addition to null. You may want `a === null ? "" : a` for maximum precision. – ggorlen Oct 08 '20 at 04:58

You can const val = a || ' '; – MubashirEbad Oct 08 '20 at 05:07
