How to convert javascript array to function

I have an array of arbitrary values. I Wrote a function that transforms the array to an array of functions that return the original values, so instead of calling a[3], I will call a3.

Here is my code which does not work? code. It gives this error Cannot call method '1' of undefined.

var numToFun = [1, 2, { foo: "bar" }];
var numToFunLength = numToFun.length;
function transform(numTo) {
 for (var i = 0; i < numToFunLength; i++) {
 (function(num){
 numTo.unshift(function() {
 return num;
 });
 }(numTo.pop())) 
 }
}
var b = transform(numToFun);
console.log(numToFun);
console.log(b[1]());​
