max value in array javascript
// For large data, it's better to use reduce. Supose arr has a large data in this case: const arr = [1, 5, 3, 5, 2]; const max = arr.reduce((a, b) => { return Math.max(a, b) }); // For arrays with relatively few elements you can use apply: const max = Math.max.apply(null, arr); // or spread operator: const max = Math.max(...arr);
