JavaScript gets the method that specifies the size of the object

This article example shows how JavaScript gets the specified object size. Share to everybody for everybody reference. The details are as follows:

function objectSize(the_object) {
 /* function to validate the existence of each key
 in the object to get the number of valid keys. */
 var object_size = 0;
 for (key in the_object){
  if (the_object.hasOwnProperty(key)) {
   object_size++;
  }
 }
 return object_size;
}

Usage:

// Arbitrary object
var something = {
 dog: "cat",
 cat: "dog"
}
console.log(objectSize(something));
// Logs: 2
