More detailed instructions on how to run the code for beginners

Hi

I think there should a sample snippet in playground.js to show how to run the scripts.

i am running it like this

// Place your playground code here.

import BubbleSort from "../algorithms/sorting/bubble-sort/BubbleSort"

const b = new BubbleSort()
const r = b.sort([99, 9, 999])
console.log(r)

&

node --es-module-specifier-resolution=node playground/playground.js

my node version v14.12.0

Pls, let me if this is the right way to test out the scripts in playgroud.

If yes I would also like to update the README.md to mention the same.

Pls let me know your thoughts

Thanks

Start with playground/playground.js and README.md, then run the example command with the documented Node.js version. Confirm how the playground scripts are intended to be run and document the sample snippet and command in README.md so beginners can reproduce the result.
