Node.js process.stdout Property

The process.stdout property is an inbuilt application programming interface of the process module which is used to send data out of our program. A Writable Stream to stdout. It implements a write() method. 

Syntax:

process.stdout.write()

Return Value: This property continuously prints the information as the data being retrieved and doesn’t add a new line.

Parameters: This property takes only single strings as an argument.

Note:

• It only takes strings as arguments. Any other data type passed as a parameter will throw a TypeError.
• It can be useful for printing patterns as it does not add a new line.
• We can not write more than one string.
• We can not make associations.

Below examples illustrate the use of process.stdout property in Node.js:

Example 1: Create a JavaScript file and name this file as index.js.

// Node.js program to demonstrate the 
// process.stdout Property 

// Printing process.stdout property value 
process.stdout.write('Greetings of the day'); 

Run the index.js file using the following command:

node index.js

Output:

Greetings of the day

Example 2: Create a JavaScript file and name this file as index.js.

// Node.js program to demonstrate the 
// process.stdout Property 

// For process.std.out  
// Association is not possible
process.stdout.write("Geeks"); 
process.stdout.write("for"); 
process.stdout.write("Geeks"); 

Run the index.js file using the following command:

node index.js

Output:

GeeksforGeeks
