var foo = 1;
var bar = 2;
var tempArray = [bar, bar = foo]; // value of foo assigned to bar and resulting value added to the array... but we ignore it. Note: it's generally poor form do assignment in this context.
foo = tempArray[0]; // grab the old value of bar from the array and assign it to foo.
console.log(tempArray);
console.log(foo);
console.log(bar);
