Update Global var with setInterval Not Working

Phaser 3
1

I have an ajax call I want to make every second to get player data like so:

//Var is globally declared
var player1type;

create() {


 setInterval(function() {	

			function gameWaitingroom(getWaitingroom) {		

				$.ajax({
					type: "GET",
					url: '../includes/waitingroomcheck.php',
					cache: false,
					success: getWaitingroom


				});

			}
					// resolve/success callback

					gameWaitingroom(result => {	
						try {
							var waitingRoomData = JSON.parse(result);
						}
						catch (error) {
							console.log('Error parsing JSON:', error, result);
						}

						//status = waitingRoomData.statusCode;
						player1type = waitingRoomData.player1type;
						console.log("INSIDE INTERVAL: "+player1type);

					});	

		},1000);

console.log("OUTSIDE INTERVAL: "+player1type);

}

My console reads like so:

INSIDE INTERVAL: user
OUTSIDE INTERVAL: undefined

Why is var player1type undefined outside of the setInterval, but it works inside just fine, even though I’ve globally declared it?

The AJAX call hasn’t been made (or received) at this point. I think the variable is fine though.
