Solutions to basic Project Euler problems in JavaScript.
So they can be quickly run in your favourite browser Developer Tools.
The project Euler problems are fun mathematical questions that can be solved algorithmically and programmatically.
Each solution includes time performance measuring:
let t0 = performance.now();
main(); // Project Euler solution
let t1 = performance.now();
console.log((t1 - t0) + " milliseconds."); // Time in ms
