Objective

In this challenge, we review some basic concepts that will get you started with this series. Check out the tutorial to learn more about JavaScript’s lexical structure.

Task

  1. 1. Use console.log() to print Hello, World! on a new line in the console, which is also known as stdout or standard output. The code for this portion of the task is already provided in the editor.
  2. 2. Use console.log() to print the contents of parameterVariable (i.e., the argument passed to main).

You’ve got this!

Input Format

Explanation 0

We printed two lines of output:

  1. 1. We printed the literal string Hello, World! using the code provided in the editor.

    return inputString[currentLine++];

function greeting(parameterVariable) {
    // This line prints 'Hello, World!' to the console:
