Is there a succinct operation in JavaScript (ES2015) that does this:
x => x === undefined ? 0 : x
I keep running into situations where I want to increment x
, but it's initially undefined, so the code becomes:
foo.bar = (foo.bar === undefined ? 0 : foo.bar) + 1;
or
foo.bar = (foo.bar ? foo.bar : 0) + 1;
Is there a less repetitive way of doing this cast?
(foo.bar || 0)
