Question

In javascript I have the following:

var inf = id + '|' + city ;

if id or city are null then inf will be null.

Is there any slick way of saying if id or city are null make then blank.

I know in c# you can do the following:

var inf = (id ?? "") + (city ?? "");

Any similar method in javascript?

Answer 1

var inf = (id == null ? '' : id) + '|' + (city == null ? '' : city)
