Setup

let array  = [1,2,3,4,5,6,7,8,9];
let array2 = [1,2,3,4,5,6,7,8,9];

function at(array, idx) {
	let val = array2[idx];
	if( val !== undefined)
	    return val
    // we should make the lazy conversion here
    // but that wouldn't be fair.
	throw 'not implemented'
}


function at2(array, idx) {
	return array2[idx] // if you already use one
}
