I spent way too long trying to debug my code when my entry was wrong for printing out "Hello World" instead of "Hello World!". The problem asks to print out "Hello World", could this please be fixed?

Having only used JS for basic website stuff, I have not seen the setup code like this:

process.stdin.resume();
process.stdin.setEncoding("ascii");
_input = "";
process.stdin.on("data", function (input) {
    _input += input;
});

process.stdin.on("end", function () {
    processData(_input);
});

What is this process object, and is it available everywhere?

"Hello World!" is different from "Hello World" -_-'

Having the JS template to read input when there's none given is going to be confusing (and looks more complicated than need be) to newcomers. Maybe the stdin template should be removed entirely, or put "Hello World!" as input and allow us to use it in:

function processData(input) {
    console.log(input);
} 

"Try it out! Write a function that prints Hello World in the console below."

There is a missing exclamation mark after "Hello World", since the submission is expecting "Hello World!"
