Getting Loopy with JavaScript

/* totally manual with a while loop */ let i = 0; while (i < 5) { console.log(`Hello, ${i}!`); i++; }; /* classic for loop */ for (let j = 0; j < 5; j++) { console.log(`Hello there, ${j}!`); } /* new-age for...of loop */ for (let k of [0, 1, 2, 3, 4]) { console.log(`Hello once more, ${k}!`); } /* using forEach with manually filled array */ [0, 1, 2, 3, 4].forEach( l => console.log(`Hello again, ${l}!`) ); /* auto-fill an array of length 5 and use indices */ Array(5).fill().forEach( (_,m) => console.log(`Hello one last time, ${m}!`) );
