The difference between call and apply in javascript

The difference between call() and apply():

Similarities:

Both () and apply() can be used to indirectly call functions, and both can explicitly call this required. That is, any function can be called as a method of any object.

2. Both methods can specify the call parameter.

 the difference:

The basic difference between call() and apply() is to pass parameters to functions.

call(): Use its own list of arguments as the function's parameters;

apply(): requires that parameters be passed in as an array.

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

Their usage can be explained by the given example:

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

var someOtherObject = {
  myProperty:'Bar'
};
(someOtherObject,'<','>');//Bar
(someOtherObject,['<','>']);//Bar
</script>
