For trick number 5, forEach seems like a fine approach, but stylistically I'm more pulled towards Reduce since Javascript doesn't have a maxBy or equivalent. const array = ["Apple", "Pine-apple", "Banana", "Jack-fruit"]; const longest = array.reduce((longest, current) => { if (longest.length < current.length) { return current; } return longest; }); console.log(longest); // Pine-apple Ternary version looks a lot cleaner, but are notoriously harder to read. const array = ["Apple", "Pine-apple", "Banana", "Jack-fruit"]; const longest = array.reduce((longest, current) => current.length > longest.length ? current : longest ); console.log(longest); // Pine-apple
