javascript中call()、apply()的区别

function track(o,m){
    var original =o[m];
    o[m] =function( ){
      console.log(new Date(),m);
      var results =original.apply(this,arguments);
      console.log(new Date(),m);
      return results;
    }
  }

<script>
var someObject = {
  myProperty:'Foo',
  myMethod:function (prefix,posfix) {
    console.log(prefix + this.myProperty + posfix);
  }
};
someObject.myMethod('<','>');//Foo

var someOtherObject = {
  myProperty:'Bar'
};
someObject.myMethod.call(someOtherObject,'<','>');//Bar
someObject.myMethod.apply(someOtherObject,['<','>']);//Bar
</script>
