JavaScript Math class offers max() functions which return the largest the given numbers respectively. We can use them to find the maximum in a JS array:
You have to use other method with max() to get max value element from array:-
- reduce()
- apply()
- Spread Operator
JavaScript max of array Code
HTML Example code:
Use reduce()
The recommended approach is to use Array.reduce() to find the maximum element in an array. It does compare each value of the array:
<!DOCTYPE html>
<html>
<body>
<script>
const max = arr => arr.reduce((x, y) => Math.max(x, y));
var arr = [ 16, 23, 35, 42, 59 ];
console.log("Max:", max(arr));
</script>
</body>
</html> Use apply()
Use the Function.prototype.apply() method for finding the maximum and minimum value in a numeric array.
<script>
var arr = [ 16, 23, 35, 42, 59 ];
console.log("Max:", Math.max.apply(null, arr));
</script> Spread Operator (…)
Use the spread operator (...) which offers the shorter syntax of writing the apply method discussed above.
<script>
var arr = [ 16, 23, 35, 42, 59 ];
console.log("Max:", Math.max(...arr));
</script> Output: Result will be same of all above example because of same array.
