How can I obtain system arguments in node.js?

Question

node helloworld.js alex

I want it to console.log() alex. How do I pass "alex" as an argument into the code?

In python ,it is sys.argv[1]

Answer 1

You can access command line arguments using process.argv in node.js.

The array also includes the node command and the application file, so the first custom command line argument will have an index = 2.

process.argv[2] === 'alex'; // true
