Node js | console.clear() Method
  • Last Updated : 14 Jan, 2020

The console.clear() method is used to clear the stdout, when stdout is a TTY (Teletype) i.e. terminal it will attempt to clear the TTY. When stdout is not a TTY, this method does nothing.

The console.clear() will work differently across different operating systems and terminal types. For Linux operating systems, console.clear() operates like the clear shell command in terminal. On Windows, console.clear() will clear the current terminal viewport for the Node.js binary.

Syntax:

console.clear()

Parameters: This method does not accept any parameters.

Below programs illustrate the console.clear() method in Node.js:



In this example, first we write the node.js command in the terminal and start node.js and then write basic command

After console.clear(), the terminal will cleared same like the clear command do in the terminal

To exit Node.js terminal press Ctrl + C two times or use .exit command.

Example:




// Node.js program to demonstrate the  
// Buffer.clear() Method
  
// Both two lines will not display
// the result on screen
console.log("GeeksforGeeks");
console.log("A computer science portal");
  
// Clear the previous screen
console.clear();
  
// Display the content
console.log("Clear the console screen");
