数组是在内存中保存一组数据的集合。实质上数组也是一种变量，不过这个变量同其他变量只能保存一个值不同，数组变量能够保存多个值，这也是数组变量同其他变量本质的区别。

 数组变量的多值性相当于一个数组变量可以包含多个子变量，而每个子变量与普通变量一样，可以被赋值，也可以从中取值。为了区别数组变量和普通变量，我们把数组的子变量称为数组元素变量（简称数组元素）。另外，把数组中数组元素的个数称为数组大小（或数组长度）。

## 数组特性

一个数组具有如下特性：

- 和变量一样，每个数组都有一个唯一的名称，称为数组名。
- 每个元素都有索引和值两个属性：索引用于定义和标识数组元素的位置，是一个从0开始的正整数；值是数组元素对应的值。
- 一个数组可以有一个或多个索引，索引的个数也称为数组的维度。拥有一个索引的数组就是一维数组，拥有2个索引的数组就是二维数组，依次类推。

 
 在JavaScript中创建数组对象有两种方式

1.使用Array对象创建数组 

```
var arrayname=newArray(arraysize)；
vararrayname=new Array(element)；
```


 在JavaScript中创建数组对象有两种方式

（1）使用“[]”创建数组

```
var arr5 =[];//创建空数组
var arr6 =["yellow","red","blue","green"];//创建颜色数组
```


 以上是创建数组的两种方式，不管使用哪种方式，都可以使用Array对象的属性和方法。但是这两种方法有区别，就是在创建空元素时，第一种方式是不允许的，第二种方式可以创建空元素。

在JavaScript中，不同的数组元素通过索引来区分，一个数组由数组名、一对方括号[]和这对方括号中的索引组合起来表示。

 例如，myArr[0]、myArr[1]、myArr[2]、myArr[3]，其中，数组元素的索引从0开始，第1个元素的索引为0，第2个元素的索引为1，依次类推，最后一个元素为myArr[arraysize-1]。



这里我们学习了Array对象，我们可以定义一个保存星期值的数组，通过数组中索引和元素一一对应的特点来实现，具体对应关系如下所示。

通过Date对象获得当前日期的星期值，使用星期值作为week数组元素的索引，从而获得星期几







## 数组元素

 我们对数组元素的赋值，既可以采用【任务实践5-7】的方式，也可以单独赋值，根据具体情况来进行。如果我们想把数组元素分别赋值给几个变量，通常采用分别赋值的方式，如下所示。

```
var arr1 = [3, 4, 5];
 var a = arr1[0];
 var b = arr1[1];
 var c = arr1[2];
 ```

在ES6标准中提供了一个新的赋值方式，称为解构赋值。解构赋值语法是一种JavaScript表达式。通过解构赋值，可以将属性/值从对象/数组中取出，赋值给其他变量。上面那段代码的简化形式如下所示。

[a, b, c] = [3, 4, 5];

length 属性用来获取数组的长度，其值为数组元素最大索引加 1。length 属性可以用于获取数组的长度，也可以用于修改数组的长度。

## 数组元素的访问

 访问数组实际上是指访问数组中的数组元素，也就是输出数组元素。在JavaScript中，输出数组元素有3种方法，分别是使用数组对象名输出数组元素、使用数组对象的索引获得元素值和使用循环语句访问数组元素。

（1）使用数组对象名输出数组元素

 该方法用创建的数组对象本身来输出数组中所有元素的值，如下代码所示。

```
var arrayObj=new Array(“a”，“b”，“c”，“d”);
document.write(arrayObj);
```
（2）使用数组对象的索引获得元素值

该方法通过数组对象的索引获得指定的元素值，如下代码所示，可以获得数组第3个元素的值。

```
var arrayObj=new Array(“a”，“b”，“c”，“d”);
document.write(arrayObj[2]);
```
 （3）使用循环语句访问数组元素

● 使用for循环语句来遍历数组元素。

使用for循环语句遍历数组元素，实际上是指通过for循环语句遍历数组所有的索引，通过索引来输出元素的值，即数组元素值=数组名[索引]。一般的代码形式如下所示。

```
var arrayObj = newArray("a", "b", "c", "d");
 for (var i = 0; i < arrayObj.length; i++) {
 document.write(arrayObj[i]);
 }
```

● 使用for…in 语句来访问数组元素。

JavaScript的for…in语句是一种特殊的for循环语句，专门用来处理与数组和对象相关的循环操作。用for…in语句来访问数组元素，可以依次对数组中的每个数组元素执行一个或多个操作。其基本的语法格式如下所示。

for(variable in array_name){
循环体//主要通过array_name[variable]来访问数组元素
}
通常执行步骤如下所示。

第1步：variable被赋值为数组的第1个元素的索引值（一般为0）。

第2步：如果variable值是一个有效的索引，就执行步骤3。

第3步：执行循环体。

第4步：variable被赋值为数组的下一个索引，转而去执行第2步，进行循环。

● 使用for…of语句来访问元素。

除以上两种for循环语句之外，ES6标准中新增了for…of 语句来访问数组元素，其基本语法如下所示。

for(value of array_name){
 循环体//主要通过value来访问数组元素
}


![image.png](https://site-1314099117.cos.ap-guangzhou.myqcloud.com/img/d7a3fd31126c0e75d9cddb81002c0a8a.image.webp)

## 数组元素的添加和删除


![image.png](https://site-1314099117.cos.ap-guangzhou.myqcloud.com/img/5bf476817ef0bf705fdc422631877ed8.image.webp)



（1）push()、pop()方法

push()用于在数组末尾添加一个或多个元素，返回值为新数组的长度。pop()用于删除数组的最后一个元素，返回值为最后一个元素。这两种方法都会改变原来的数组，具体示例代码如图5-21所示。

（2）shift()、unshift()方法

unshift()用于在数组开头添加一个或多个元素，返回值为新数组的长度。shift()用于删除数组的起始元素，返回值为起始元素。这两种方法都会改变原来的数组，具体示例代码如图5-22所示。

（3）concat()方法

concat()方法用于连接多个数组，返回新连接的数组，但是不改变原来的数组，具体示例代码如图5-23所示。



![image.png](https://site-1314099117.cos.ap-guangzhou.myqcloud.com/img/f219b80b52c833705ba17bf30597b1aa.image.webp)

（4）splice()方法

splice()方法可以在数组的任意位置实现添加、替换、删除数组元素的操作，语法格式如下所示。

```
arrayObject.splice(start,length,element1,element2,…) 
```

第一个参数是数组的起始位置，第二个参数是删除的个数，从第三个参数开始是数组的添加元素，返回值为删除的元素数组，这个方法会改变原数组。

① 添加操作，将第二个参数设置为0，如图5-25所示。

② 替换操作，设置第二个参数，如图5-26所示。

③ 删除操作，第三个及以后的参数不需要设置，如图5-27所示。




![image.png](https://site-1314099117.cos.ap-guangzhou.myqcloud.com/img/f8ddd8657ca8f267b9e36c9b748c6f93.image.webp)

## 数组的排序

（1）reverse()方法

 reverse()方法用于颠倒数组中元素的顺序，返回改变后的数组，如图5-28所示。

（2）sort()方法


![image.png](https://site-1314099117.cos.ap-guangzhou.myqcloud.com/img/958fbf7c245c3bb64b82c230e65a7697.image.webp)
 sort()方法用于按照字符串的字典顺序对数组元素进行排序，如图5-29所示。



![image.png](https://site-1314099117.cos.ap-guangzhou.myqcloud.com/img/2b838b5b824172500627901c998e75e7.image.webp)

    可以说black beauty经历的事实在是太多了，比如幼年时受到良好的教育，成年后套上笼头，受伤后被抛卖，老年后被好心人买回。这一辈子，经历了好主人，也有坏主力；有乐，更有苦。被卖给一个贵族时，贵族酒驾，导致马伤人亡；被卖去当出租马时，出租人豪不怜惜马力，使命鞭打；被当作苦力马时，主力一直往身上压重担，直至压垮倒地；直至老年，身体备受摧残，只能沦为劣质马。
    听过、见过的故事就更多了，同伴Ginger的过往被主人欺负压榨的故事，马匹的马尾被切除仅仅是为了时尚，老战马回忆战场的经历，拉煤马Rory每日在生死线上苦苦挣扎……种种这些，其实何尝不是底层人们的命运，一切都是身不由己！

Black Beauty 黑神驹

不愧是大刘，想象力极其丰富。科技的发展，最终会迎来什么样子？人类也许在不知不觉之间就被毁灭了。球状球状闪电的悬疑、奇特事迹说起，一步一步进行揭秘球状闪电的科学原理，最终将球状闪电应用到军事领域，发展出无法想象的宏原子炸弹。虽然是一本科幻小说，但是里面也道尽了无数的人生哲学和为人处世之道。比如说故事中的张老师，一辈子追求的科研，却处处碰壁；林云的武器言论，是对是错？

**第三章 序曲**

    看完书籍后再来看这一句话，感触良多！生命如此脆弱，不经意间就烟消云散！
    
    > 原文：孩子，这就是生命和人生，脆弱而飘忽不定，经不起一丝微风。

    又掌握了一个知识点，两千度的高温。开场就是如此诡异，一个球状闪电，将两个活生生的人化为了乌有。也为本书的开场提供了足够的悬念
    
    > 原文：在火葬场的炉子中，要把人体完全化为灰烬，要在两千度的高温下烧三十分钟

**第五章 大学**

    人生到底是什么？ 人为什么活着？有些哲学的意味
    
    > 原文：“美妙人生的关键在于你能迷上什么东西。”我现在真正体会到他这话的正确，我现在的人生好比一颗疾飞的炮弹，除了对到达目标时那一声爆炸的渴望之外什么都没有。这个目标完全是非功利的，达到它就意味着生活的完结，我不知道为什么要去那儿，我只是想去，这就够了，这是人类最本源的冲动

**第一十三章 西伯利亚**

    可悲可叹！人在世道中，确实是如此卑微，一生又如何，也就是默默无闻的一辈子
    
    > 原文：在那个可悲的理想主义年代，有一群共青团员来到了西伯利亚的密林深处，在那里追逐一个幽灵，并为此献出了一生……

**第三十六章 特别领导组**

- **2024/04/01 发表想法**
    
    宏原子核的想法，真是奇幻！人类的科技，未来真的不知道会发展到哪一步，也许不知不觉间就面临了世界末日。现实中的原子弹爆炸是如此恐怖，而宏原子核爆炸又是一个怎么样的灭世场景？
    
    > 原文：捕获宏原子核（现在都被称为弦）的工作一直没有中断，当基地的迁移最后完成时，已经捕获和存贮了近三百根弦

娱乐，刘慈欣

头脑清醒者，总是无法被人接受。

轻松、娱乐

    非常有想象力的一本书籍，以科幻的名义，从另外一种角度提出了一种恐龙灭亡的可能性。也提出了地球家园是相互依存的一种关系，而不是你死我活的竞争。
