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 −
