Node.js | Buffer.values() Method

Buffer is a temporary memory storage which stores the data when it is being moved from one place to another. It is like an array of integers.

The Buffer.values() Method is used to create a loop or iterating object which contains value of each byte of buffer instance. This method is called automatically when a Buffer is used in a for…of statement.

Syntax:



Buffer.values()

Return Value: It returns an iterator looping through each byte of the buffer.

Below examples illustrate the use of Buffer.values() Method in Node.js:

Example 1:

filter_none

edit
close

play_arrow

link
brightness_4
code

// Node.js program to demonstrate the  
// Buffer.values() Method
const buffer = Buffer.from('geek');
   
// Display the buffer ASCII character
for (const value of buffer.values()) {
      console.log(value);
}

Output:

103
101
101
107

Example 2:

filter_none

edit
close

play_arrow

link
brightness_4
code

// Node.js program to demonstrate the  
// Buffer.values() Method
const buffer = Buffer.from('geek');
   
// Display the ASCII values
for (const value of buffer.values()) {
  console.log(value);
}
// Prints:
// 103
// 101
// 101
// 107
   
const buffer2 = Buffer.from('GEEK');
   
// Display the ASCII values
for (const value of buffer2.values()) {
  console.log(value);
// Prints:
// 71
// 69
// 69
// 75
  
var op = Buffer.compare(buffer, buffer2);
console.log(op); 
// Prints: 1 
// As buffer is higher than buffer2 i.e if
// Buffer should come before buffer2 when sorted.

Output:

103
