javascript - How can I coerce a check for a variable being defined or not into a string reading True or False? -

i have console logs set this:

console.log("getteststatusactions" + this.userteststatusactions === undefined);

this gives output single word "false".

how can create output of be:

"getteststatusactions: userteststatusactions defined"

or

"getteststatusactions: userteststatusactions undefined"

ternary!

console.log("getteststatusactions" + (this.userteststatusactions === undefined ? "undefined" : "defined"));

or, readability:

var status = this.userteststatusactions === undefined ? "undefined" : "defined"; console.log("getteststatusactions: userteststatusactions " + status);
