Findind it difficult to code a particular practice exercise

const random = Math.floor(Math.random() * 100);
const array = ;
for (var i = 0; i <= random; i++) {
let sumArray = ;
for (var n = 0; n < random; n++) {
sumArray += array.push(n);

this is my code in Javascript
the top coed works fine but the base does not complete it well…

i was trying to generate a random number and create an array from it that will begin at 1 and end at that random number
then i will sum the numbers in th array using .reduce() and divide the answer by the random number(which is the highest number in the array)…

If you add 1 it will include 100 in the array (potentially), and will not include 0.

Math.floor(Math.random() * 100) + 1


Math.floor(Math.random() * 100 + 1)

Either way comes out the same.

There is a bit of a type match problem there. Isn’t sumArray an array? And, isn’t array.push(n) a statement?

There is a strong possibility that array.push() does return a value, the new length of the array, so in that sense it would be an expression. The .reduce you are working toward could be to set sumArray to a zero value, rather than an empty array. Then the above line would work, accordingly.

 > array = []
<- []
 > sum = 0
<- 0
 > for (let i = 1; i < 101; i++) {
       sum += array.push(i)
<- 5050
