Get the largest value from an array using javascript

Get the largest value from an array using javascript

To get the largest value from an array:

1. Create an array eg. - arr = [50, 20, 60, 90, 30, 70].
2. Use Math.max() function to get the largest value from the array. eg. Math.max(...arr).

Using Math.max() function

The Math.max() function in JavaScript is used to return the largest value from a given array of numbers. It takes an array of numbers as an argument and returns the number with the highest value in the array.
It is a built-in function used to find the largest number in the array. It is a very useful and convenient tool for quickly determining the largest value from an array of numbers. This function can be used to quickly and easily find the maximum value for a given array of numbers.
We will also use the spread operator in Math.max() function.

Syntax

Math.max(...array)

const arr = [50, 20, 60, 90, 30, 70];

const max_val = Math.max(...arr);

console.log(max_val);

Output

90

This code snippet declares a constant array and assigns it some values. It then declares a constant called max_val and assigns it the value of the highest number in the array using the Math.max() method with the spread operator. Finally, it prints the value of max_val to the console.

Using for loop

function largest_val(arr) {
    let max = arr[0];
    for (let i = 1; i < arr.length; i++) {
        if (arr[i] > max) {
            max = arr[i];
        }
    }
    return max;
}

const max_val = largest_val([50, 20, 60, 90, 30, 70]);

console.log(max_val);

Output

90
