我得到TypeError对象ABCD有没有方法比较？

Question

JS比较缓冲器

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. 你必须从缓冲区1修改变量和缓冲区2缓冲器1和缓冲器，因为JS不允许这个语法结构来创建变量。 JS中的变量名称之间不允许有空格。 检查你的控制台，它会给你语法错误：意外的数字。

2. 下面是修改代码来获得缓冲区匹配：

   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"); 
   }
