+数组 : 引用型(对象 增删改查)，基本数据类型(值类型)
+增:
+ arr[10] = 'java'
+
+ 查 ： arr[index]
+
+ 改
+ arr[1] = "五"
+
+ 删:
+ delete arr[0];
+
+
+ 增加: push, pop , shift, unshift 链表 队列
+ arr.pop() //删除最后一个元素
+ arr.push(4,5,6) //在数组末尾添加元素
+ arr.shift() //删除第一个元素
+ arr.unshift(4,5,6) //往数组头部添加元素
+排序：sort():根据字符串顺序排序，不是按照数字大小排序
+
+reverse()反转数组
+
+splice():嫁接(裁掉不需要，需要的接上去)
+delete count
+
+ splice(index,delecount,insertvalue):下标index开始，删除delecount个元素
+ 再添加inservalue
+ 只删除， 替换， 添加
+ arr.splice(3,0,'嫁','接',666); //替换作用
+
+
+ console.log(String.prototype);
+ console.log(str.toUpperCase()); 大小写转换
+
+ console.log(str.substr(4,6));
+ console.log(str.substring(4,0)); //[4,6) 如果start>end,交换顺序
+ console.log(str.trim()); //去掉两边的空格，中间穿插的不可以

+ console.log(str.includes('Sc'));//返回true表示找得到，返回false表示找不到
+ console.log(str.indexOf('Sc',6)); //返回的是第一个匹配字符串的起始下标,如果找不到返回-1
+ console.log(str.slice(4,0)); //截取,返回对应长度的字符串
