Question

JS比较缓冲区

我想比较这两个缓冲区对象：

var buffer 1 = new Buffer("ABED");
var buffer 2 = new Buffer("ABED");
var result = buffer 1.compare(buffer 2);

//console.log(result);
if(result < 0) {
    console.log(buffer 1 + " comes before " + buffer 2);
} else if(result === 0){
           console.log(buffer 1 + " is same as " + buffer 2);
       } else {
                console.log(buffer 1 + " comes after " + buffer 2);
              }

您必须将变量从缓冲区1和缓冲区2更改为buffer1和buffer2，因为JS不允许使用此语法结构来创建变量。 不得在JS中的变量名之间留出空格。 检查您的控制台，它会为您提供语法错误：意外编号。

以下是获取Buffers Matched的修改代码：

var buffer1 = new Buffer("ABED");

var buffer2 = new Buffer("ABED");

var first = buffer1.toString();

var second = buffer2.toString();

if(a === b) {
  console.log("Buffers Matched");
}

我得到TypeError对象ABCD有没有方法比较？
