optimized, and efficient way of calculating the sum of array elements is the use the reduce() method in javascript and write a reducer function or callback for it that will return the accumulated value.

In the given problem statement we are asked to calculate the difference between the first and second element of each subarray separately and we have to return the sum of their differences with the help of javascript functionalities. In the ...
We are required to write a JavaScript function that takes in an array of numbers sorted in increasing order. Our function should calculate the variance for the array of numbers. Variance of a set of numbers is calculated on the basis of their mean. Mean(M)=(∑n−1i=0arr[i])Mean(M...

Destructure the array to get x1, y1, x2 and y2. Calculate the midpoint for each dimension by dividing the sum of the two endpoints by 2.
Use Array.prototype.reduce() to calculate how many numbers are below the value and how many are the same value and apply the percentile formula. Sample Solution: JavaScript Code: // Define a function 'percentile' that calculates the percentile of a given number in an arrayconstpercentile=(arr...
