How can I make a function to find average from a number insert from prompt? Instead of an array of data.
It is different form all the tutorial on the site because the tutorial and solution here are having a set of data already but instead this question above wants us to calculate the sum of the input number form the prompt.
for example:
const size = parseInt(prompt("insert number")) + 1;
if(size > 0){
const arr = [...Array(size).keys()];
const sum = arr.reduce(function(a, b) { return a + b; }, 0);
alert(sum / size );
}
