Verdict

, Chrome, and TextMate. 

Firefox

In Firefox, there's a minimum width beyond which the tabs will not shrink. Tabs that cannot fit into the real estate are hidden, but can be gotten to via the left and right scroll arrows(on the left and right of the tabs) or via the tab drop-down icon on the far right.

Safari

Safari works similar to Firefox, except that it does not have the left and right arrows.

IE 7

Chrome

TextMate

var dan = new Man('Dan')

How do?
Hello, John, my name is Dan

Code Size

function sqrt(a, b){

    return a * 2 + b * 2;

}

function sqrt(a, b, callback){

    multiply(a, 2, function(a2){

        multiply(b, 2, function(b2){

            add(a2, b2, callback);

}

Readability

Code is Coupled to Ordering of Operations

function sqrt(a, b){
    var a2 = a * 2;
    var b2 = b * 2;
    return a2 * b2;
}

function sqrt(a, b, callback){
    multiply(a, 2, function(a2){
        /* code */
        multiply(b, 2, function(b2){
            /* code */
        });
        /* more code here */
    });
}

  var _f = function(){
    var callback = arguments[arguments.length - 1];
    var args = Array
      .prototype.slice
      .call(arguments, 0, arguments.length - 1)
    var retVal = f.apply(this, args)
    if (callback) callback(retVal)
  }
  _f.name = f.name
  return _f
}

function add(one, other){
  return one + other;
}

add = asCPS(add)

add(1, 2, function(sum){
  console.log('sum: ' + sum)
})
