Resolve #439

For now, I choose to use Node.js version v18 as the Grader Runtime.

Local Testing:

Example submission file for the A+A problem:

"use strict";
 
process.stdin.resume();
process.stdin.setEncoding("utf-8");
 
let inputString = "";
let currentLine = 0;
 
process.stdin.on("data", (inputStdin) => {
    inputString += inputStdin;
});
 
process.stdin.on("end", (_) => {
    inputString = inputString
        .trim()
        .split("\n")
        .map((string) => {
            return string.trim();
        });
 
    main();
});
 
function readline() {
    return inputString[currentLine++];
}
 
function print(data) {
    console.log(data);
}
 
function main() {
    let n = Number(readline());

    print(n*2);
}

Thanks for the contribution! Really appreciated it.

However, we currently are punting the initiatives of adding language support for "non-CP" languages (JS, TS, PHP). This is because for it to be effective, we need to support "function-style" submission. By this I mean contestants can just fill a skeleton and submit it:

function add(a, b) {
  return 0; // complete here
}

without actually reading the inputs from stdin, which is not really convenient and intuitive.

The current infrastructure still does not support this.

We may revisit this in the future, but I'll keep this PR open. 😄

Hi @fushar , when you say 'keep this PR open,' do you mean to keep it open until the infrastructure supports functional-style submission or until I have resolved the previous comments?

Btw, platforms like Codeforces also support Node.js (https://codeforces.com/contest/1881/submission/229061225). Maybe keeps both functional-style and input-output submissions? This PR is for handling the input-output submission. Wdyt?

I'm sorry, but I'd delay it until the infra supports / there is use case. Reasons:

  1. JavaScript is not still popular for CP,
  2. we are increasing the Docker image size of the grader without justified reason.

Okay, I will reopen this PR, but on a different branch. I accidentally used my master branch as the base branch, so I cannot contribute next time until this PR is merged.
