max number from a array 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: maximum number from Array
---without sort method---
public static int maxValue( int[] n ) {
int max = Integer.MIN_VALUE;
for(int each: n)
if(each > max)
max = each;
return max;
---with sort method---
public static int maxValue( int[] n ) {
Arrays.sort( n );
return n [ n.lenth-1 ];
}
