Return Value: This property returns a string signifies the absolute path of the node.js executable which started the node.js process.
Below examples illustrate the use of process.execPath property in Node.js:
Example 1: 
 

// Node.js program to demonstrate the  // process.execPath property // Include process module const process = require('process'); // Printing process.execPath console.log(process.execPath); 

Output: 
 

C:\Program Files\nodejs\node.exe

Example 2: 
 

// Node.js program to demonstrate the  // process.execPath property // Include process module const process = require('process'); // Include path module const path = require('path');   // Printing process.execPath var execpath = process.execPath console.log(execpath); // Separated directories and file console.log(execpath.split(path.sep)); 

Output: 
 

C:\Program Files\nodejs\node.exe [ 'C:', 'Program Files', 'nodejs', 'node.exe' ]

Note: The above program will compile and run by using the node filename.js command.
