In jquery, by accumulating the array elements and dividing by the length of the array, the average of the array can be obtained.
Create a new html file, named test.html, to explain how jquery calculates the average of an array. Within the js tag, create an array and initialize a variable $sum.
Use a for loop to traverse the array to accumulate array values. Get the length of the array through the length attribute, and then divide the sum of the array values by the length to get the average of the array. Use the write() method to output the calculated results.
Open the test.html file in the browser to view the results.
