get max value of an array in js code example

Example 1: 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);

Example 2: how to find max in array

int[] a = new int[] { 20, 30, 50, 4, 71, 100};
		int max = a[0];
		for(int i = 1; i < a.length;i++)
		{
			if(a[i] > max)
			{
				max = a[i];
			}
		}
		
		System.out.println("The Given Array Element is:");
		for(int i = 0; i < a.length;i++)
		{
			System.out.println(a[i]);
		}
		
		System.out.println("From The Array Element Largest Number is:" + max);
