Javascript : Good parts

Simplest thing is hard

for loop

for (i in someArray){ }

for (var i in someArray) { }

for (var i in someObject) { }

Don't use setTimeout for timing

not guarantee

var remoteValue = false;
$.ajax({

  url: 'http://google.com',

  success: function() {

    remoteValue = true;

  }
});
 
console.log(remoteValue); //outputs "false"
