Is there some syntactic sugar I can use to set a JS variable to "" if it's null?

I want to set a variable to an empty string in Javascript, a pretty routine thing. I just don't know how to do it without doing this:

if (existingnote==null) {
  existingnote = "";
}

Is there a faster or easier way?

There is now shorthand for @DaveNewton answer

Logical OR Assignment

let existingnote = null

existingnote || = "";

console.log(existingnote)

If you want just null to work this way, try

existingnote = (existingnote === null? "": existingnote);

existingnote = existingnote || "";

This checks for truthy/falsy, which may not be what you want.
