How to mimick the functionality of the SQL Coalesce statement in Javascript

Question

I was wondering if there is a way in javascript to have logic similar to the coalesce statement in sql which will return data in a specified order like this:

Select top 1 Coalesce(ColA, ColB, "No Data Found") from TableA;

is there an elegant way to deal with null values in Javascript, the same way that sql returns results in the above statement?

i know i could technically have a switch statement, but this would require some possibly unnecessary code

Thank you.

Answer 1

You can use an OR.

 var someVar = null || value;
 var otherVar = null || variableThatEvaluatesToNull || functionThatEvaluatesToNull() || value;
