as a "high-integrity" function:
var freeze = Object.freeze,
push = Function.prototype.call.bind(Array.prototype.push);
function makeTable() {
var array = [];
return freeze({
add: function(v) { push(array, v); },
store: function(i, v) { array[i >>> 0] = v; },
get: function(i) { return array[i >>> 0]; }
});
}
Careful there, you're not done!-) With nodejs, adding the following
var table = makeTable();
table.add(1);
table.add(2);
table.add(3);
var secret;
Object.defineProperty(Array.prototype,42,{get:function(){ secret = this;}});
table.get(42);
console.log(secret);
secret[5] = "me, too!";
console.log( table.get(5) );
to your code prints
$ node integrity.js
[ 1, 2, 3 ]
me, too!
Couldn't resist,
