How to Find the Max and Min Values of an Array in JavaScript

Topic: JavaScript / jQueryPrev|Next

Answer: Use the apply() Method

You can use the Math.max() and Math.min() methods in combination with the apply() method to find the maximum or minimum values within an array or an array-like object, like this:

<script>
var numbers = [1, 5, 2, -7, 13, 4];
    
var maxValue = Math.max.apply(null, numbers);
console.log(maxValue); // Prints: 13
    
var minValue = Math.min.apply(null, numbers);
console.log(minValue);  // Prints: -7
</script>

See the tutorial on JavaScript borrowing methods to know the reason for using the apply() method here. Alternatively, you can use the ES6 spread operator to perform the same task.

<script>
var numbers = [1, 5, 2, -7, 13, 4];
    
var maxValue = Math.max(...numbers);
console.log(maxValue); // Prints: 13
    
var minValue = Math.min(...numbers);
console.log(minValue);  // Prints: -7
</script>
