Slip 5 - A) Create a Node.js Application that performs following operations on Buffer data.

 Solution:

buffer_op.js

var buffer1 = new Buffer('TutorialsPoint ');

var buffer2 = new Buffer('Simply Easy Learning');

var buffer3 = Buffer.concat([buffer1,buffer2]);

console.log("buffer3 content: " + buffer3.toString());

var result = buffer1.compare(buffer2);

if(result < 0) {

   console.log(buffer1 +" comes before " + buffer2);

} else if(result === 0) {

   console.log(buffer1 +" is same as " + buffer2);

} else {

   console.log(buffer1 +" comes after " + buffer2);

}

buffer1.copy(buffer2);

console.log("buffer2 content: " + buffer2.toString());

 

Initiate buffer_op.js file :

C:\Users\Your Name>node buffer_op.js
