Is your TypeScript spread functionality not functioning as expected?

I'm new to TypeScript, so please forgive me if I've made an error.

On a guide about TypeScript that I found online, it states that the following TypeScript code is valid:

function foo(x, y, z) { }
var args = [0, 1, 2];
foo(...args);

However, when I try to compile my TypeScript using tsc *.ts --watch --target ES6, I receive an error message saying 

error TS2346: Supplied parameters do not match any signature of call target.

Isn't this supposed to work correctly? It seems like a simple task, so what could be going wrong?

Check out this code snippet here

function foo(x:number, y:number, z:number):void {
console.log(x,y,z);
}
let args:number[] = [0, 1, 2];
foo(...args);
