Day 0: Hello, World! | Problem

As an experienced developer, I want to share my perspective on the Day 0 “Hello, World!” challenge. Frankly, this is the most convoluted “Hello, World!” exercise ever, I’d expect beginners to somewhat struggle when a Hello World exercise should be just for teaching the very basic syntax.

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. Use console.log() to print the contents of  (i.e., the argument passed to main).

function greeting(parameterVariable) {
    console.log('Hello, World!');
    console.log(parameterVariable);
}
