javascript - 我收到 TypeError Object ABCD has No method compare?

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);
              }

Answer 1

1. 您必须将变量从缓冲区 1 和缓冲区 2 更改为缓冲区 1 和缓冲区 2，因为 JS 不允许使用这种语法结构来创建变量。 JS中变量名之间不能有空格。检查你的控制台，它给你语法错误:意外数字。

2. 这里是获得匹配缓冲区的修改代码:

   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");
   }
