Find the average of all elements of array except the largest and smallest - JavaScript

We are required to write a JavaScript function that takes in an array of Number and returns the averages of its elements excluding the smallest and largest Number.

Let’s write the code for this function −

Following is the code −

const arr = [1, 4, 5, 3, 5, 6, 12, 5, 65, 3, 2, 65, 9]; const findExcludedAverage = arr => {    const creds = arr.reduce((acc, val) => {       let { min, max, sum } = acc;       sum += val;       if(val > max){          max = val;       };       if(val < min){          min = val;       };       return { min, max, sum };    }, {       min: Infinity,       max: -Infinity,       sum: 0    });    const { max, min, sum } = creds;    return (sum - min - max) / (arr.length / 2); }; console.log(findExcludedAverage(arr));

Output

Following is the output in the console −
