sharedArrayBuffer.slice
sharedArrayBuffer.slice
SharedArrayBuffer.prototype.slice() 方法返回一个新的SharedArrayBuffer 其内容是该SharedArrayBuffer的字节从开始包含，直到结束，独占的副本。如果开始或结束是负的，它指的是从数组末尾开始的索引。此方法与 Array.prototype.slice() 具有相同的算法。
句法
sab.slice()
sab.slice(begin)
sab.slice(begin, end)
参数
begin基于零的索引开始提取。可以使用负索引，指示从序列末尾开始的偏移量。
返回值
一个新的SharedArrayBuffer包含提取的元素。
示例
var sab = new SharedArrayBuffer(1024
sab.slice( // SharedArrayBuffer { byteLength: 1024 }
sab.slice(2 // SharedArrayBuffer { byteLength: 1022 }
sab.slice(-2 // SharedArrayBuffer { byteLength: 2 }
sab.slice(0, 1 // SharedArrayBuffer { byteLength: 1 }
