That's because a and b are still naming the same object.
A circumstance where two or more variables refer to the same object.
And here user stores the reference to the same object all the time.
Is not a is not b a andb are not exactly the same object.为了查看两个变量是否指向同一个对象,你可以使用is运算符。
To check whether two variables refer to the same object, you can use the is operator.Combinations with other parts of speech
但是,如果sp1与sp2指向同一个对象,共享引用计数信息时呢?
But what if sp1 and sp2 are pointing to the same object and so share a reference count?Exports是同一个对象-所以它们实际上是对单个对象的相同引用:.
Exports is the same object- so they are actually the same reference to a single object:..举个例子,两个变量引用同一个对象的情况下,它们就是相等的:.
For instance, two variables reference the same object, they are equal:.对象具有个性,并且多个名称(在多个范围中)可以绑定到同一个对象。
Objects have individuality, and multiple names(in multiple scopes)can be bound to the same object.
A circumstance where two or more variables refer to the same object.他继续说:“你看到发生了什么事当两股力量同时工作在同一个对象。
He continued:"You saw whathappened when two forces worked simultaneously on the same object.对象具有个性,多个名称(在多个作用域内)可以绑定到同一个对象。
Objects have individuality, and multiple names(in multiple scopes)can be bound to the same object.您可以使用parameter在构造函数的主体内部经常使用它,它总是表示同一个对象。
You can use parameter as often as you like inside the body of the constructor,and it always denotes the same object.这里,我们保持传递的对象的参考,并在同一个对象附加的值。
Here, we are maintaining reference of the passed object andappending values in the same object.如果另一个列表有同样的元素,我们说它们有相同的值,但是它们并不是同一个对象。
If another list has the same elements, we say it has the same value,but it is not the same object.
This situation is known as aliasing: both variables refer to the same object.C允许(至少也没有禁止)不同的源文件具有同一个对象的tentativedefinition。
C then allows(or at least does not forbid)different source files to have tentative definitions for the same object.
In this example, there are two references to the same object.所有被访问的对象都被记住,以便以后不再访问同一个对象两次。
All visited objects are remembered,so as not to visit the same object twice in the future.如果promise和x是同一个对象,则promise变成rejected,reason是一个TypeError异常。
It's as ifyou are using different filters when looking at the same object.”.记住,你只能使用self变量来参考同一个对象的变量和方法。
Remember, that you must refer to the variables and methods of the same object using the self only.如果一个线程频繁调用该方法,其他线程若也需要频繁的同步访问同一个对象通常会被阻塞。
If one thread invokes this method frequently,other threads that also need frequent synchronized access to the same object will often be blocked.对象是被特化的,多个名字(在多个作用域中)可以绑定同一个对象。
Objects have individuality, and multiple names(in multiple scopes)can be bound to the same object.需要注意的是,在ECMAScript中,同一个父上下文创建的若干个内部函数的闭包的[[Scope]]是同一个对象。
It is necessary to notice that closured[[Scope]] in ECMAScript is the same object for several inner functions created in this parent context.Copy1中的x属性与copy2中的x属性引用了内存中同一个对象,因此严格等于(strictequality)运算符返回true.
The x property in copy1 refers to the same object in memory that x in copy2 refers to, so the strict equality operator returns true.
Being the same object(which implies equivalence).
As can be seen it is indeed the same location.
Obj2 and obj1 are considered to be the same object.
