javascript closure immediate evaluation [duplicate]

Answer 1

Just another approach, using currying:

var a = [];
var f = function() {
    for (var i = 0; i < 3; i++) {
        a.push((function(a){alert(a);}).curry(i));
    }
    for (var j = 0; j < 3; j++) {
        a[j]();
    }
};

// curry implementation
Function.prototype.curry = function() {
  var fn = this, args = Array.prototype.slice.call(arguments);
  return function() {
    return fn.apply(this, args.concat(
      Array.prototype.slice.call(arguments)));
  };
};
