对象自身用处不大，不过在了解其他类之前，还是应该了解它。因为 ECMAScript 中的 Object 对象与 Java 中的 java.lang.Object 相似，ECMAScript 中的所有对象都由这个对象继承而来，Object 对象中的所有属性和方法都会出现在其他对象中，所以理解了 Object 对象，就可以更好地理解其他对象</span><strong>。</strong></p>\r\n<p style="margin-left: 30px;" align="left"> javascript引用数据类型是保存在堆内存中的对象，JavaScript不允许直接访问堆内存空间中的位置和操作堆内存空间，只能通过操作 对象在栈内存中的引用地址。所以引用类型的数据，在栈内存中保存的实际上是对象在堆内存中的引用地址。通过这个引用地址可以快速查找到保存在堆内存中的对象。下面我们来演示这个引用数据类型赋值过程<br>\r\n</p>\r\n<p style="margin-left: 30px; text-align: left;"> <img style="display: block; margin-left: auto; margin-right: auto;" src="http://images2015.cnblogs.com/blog/748999/201511/748999-20151105194829696-589797035.png" alt=""></p>\r\n<p style="text-align: left; margin-left: 30px;">自然，给obj2添加name属性，实际上是给堆内存中的对象添加了name属性，obj2和obj1在栈内存中保存的只是堆内存对象的引用地址，虽然也是拷贝了一份，但指向的对象却是同一个。故而改变obj2引起了obj1的改变。 </p>\r\n<p style="margin-left: 30px;" align="left">基本类型值指的是那些保存在栈内存中的简单数据段，即这种值完全保存在内存中的一个位置。而引用类型值则是指那些保存在堆内存中的对象，即变量中保存的实际上只是一个指针，这个指针指向内存中的另一个位置，该位置保存对象。</p>\r\n<p style="text-align: left; margin-left: 30px;">简而言之，堆内存存放引用值，栈内存存放固定类型值。 </p>\r\n<p style="margin-left: 30px; text-align: left;"><img style="display: block; margin-left: auto; margin-right: auto;"

中，变量可以存在两种类型的值，即原始值和引用值。原始值存储在栈（stack）中的简单数据段，也就是说，它们的值直接存储在变量访问的位置。引用值存储在堆（heap）中的对象，也就是说，存储在变量处的值是一个指针（point），指向存储对象的内存处。</p>\r\n<div class="cnblogs_code"><div class="cnblogs_code_toolbar"><span
