Filter out the values you want to skip before using forEach. This way, you avoid unnecessary iterations and can control when to stop. let numbers = [1, 2, 3, 4, 5]; numbers .filter(number => number != 4) .forEac
foreach2.js let stones = new Map([[1, "garnet"], [2, "topaz"], [3, "opal"], [4, "amethyst"]]); stones.forEach((k, v) => { console.log(`${k}: ${v}`); }); We have a small map of stones. In each loop, the pair is destructured into a key and a value. ...
