To find the minimum or maximum element in a JavaScript array, use Math.min or Math.max with the spread operator.

JavaScript offers several methods to achieve this, each with its advantages.

Using Math.min() and Math.max() Methods

The Math object’s Math.min() and Math.max() methods are static methods that return the minimum and maximum elements of a given array.

The spread(…) operator could pass these functions into an array.

JavaScript

let Arr = [50, 60, 20, 10, 40]; let minVal = Math.min(...Arr);  let maxVal = Math.max(...Arr); console.log("Min Elem is:" + minVal); console.log("Max Elem is:" + maxVal);

Output

Minimum element is:10 Maximum Element is:60

Math.min(…Arr) and Math.max(…Arr) find the smallest (10) and largest (60) values in [10, 20, 30, 40, 50, 60], logging “Min Elem is: 10” and “Max Elem is: 60”.

Iterating through the Array

Iterate through the array, initializing the minimum and maximum values to Infinity and -Infinity, respectively.

JavaScript

let Arr = [50, 60, 20, 10, 40]; let minVal = Infi; let maxVal = -Infi;  for (let item of Arr) {  // Find min val   if (item < minVal)       minVal = item;  // Find max val    if (item > maxVal)        maxVal = item; console.log("Min elem is:" + minVal); console.log("Min elem is:" + maxVal); }

Output

Min elem is:50 Min elem is:50 Min elem is:50 Min elem is:60 Min elem is:20 Min elem is:60 Min elem is:10 Min elem is:60 Min elem is:10 Min elem is:60

minVal and maxVal are initialized to Infinity and -Infinity.
The for...of loop updates minVal and maxVal by comparing each array element.
The console.log statements print the minimum and maximum values during every iteration (which should be outside the loop).

Using a Custom Comparator with Array.sort() Method

The Array.sort() method sorts the elements of an array in place and returns the sorted array..

JavaScript

let Arr = [50, 60, 20, 10, 40]; Arr.sort((a, b) => a - b);  let minVal = Arr[0];  Arr.sort((a, b) => b - a);  let maxVal = Arr[0];    console.log("Min Elem is:" + minVal); console.log("Max Elem is:" + maxVal);

Output

Minimum element is:10 Maximum Element is:60

The array is sorted in ascending order for the minimum and descending order for the maximum.
The first element after each sort gives the result, but sorting modifies the array.
