Introduction

Following is the syntax of the method to write into a Node Buffer:

buf.write(string[, offset][, length][, encoding])

This method returns number of octets written.

If there is not enough space in the buffer to fit the entire string, it will write a part of the string.

// example//from  w  w w. j  av  a  2  s  . c  o m
var buf = Buffer.alloc(256);
len = buf.write("Simply Easy Learning");
console.log("Octets written : "+  len);
