Поправил код, сам код выполняю в блоке node.js. Но среднее значение не считается, вместо него пустое значение
"[853374032] [00:39:30] Поток №1 : Average popularity:"
Исправленный код:
const victorianSlang = [ { term: 'doing the bear', found: true, popularity: 108, }, { term: 'katterzem', found: false, popularity: null, }, { term: 'bone shaker', found: true, popularity: 609, }, { term: 'smothering a parrot', found: false, popularity: null, }, { term: 'damfino', found: true, popularity: 232, }, { term: 'rain napper', found: false, popularity: null, }, { term: 'donkey’s breakfast', found: true, popularity: 787, }, { term: 'rational costume', found: true, popularity: 513, }, { term: 'mind the grease', found: true, popularity: 154, }, ]; let popularitySum = 0; let itemsFound = 0; const len = victorianSlang.length; let item = null; for (let i = 0; i < len; i++) { item = victorianSlang[i]; if (item.found) { popularitySum = item.popularity + popularitySum; itemsFound = itemsFound + 1; } }; const averagePopularity = popularitySum / itemsFound; console.log("Average popularity:", averagePopularity);
