add number as long index in array-CodePudding

I have data like this

let number = 1000
let array = [1,2,3,4,5]
let percentage = 5%

and the output I expected is

array1 = 1000 5%
array2 = 1000 5% 5%
array3 = 1000 5% 5% 5%
array4 = 1000 5% 5% 5% 5%
array5 = 1000 5% 5% 5% 5% 5%

I'm trying add more percentage as the index, I have tried with for loop, but none is working.

can anyone help me with the logic ?
any help is appreciated. Thank you

I tried to understand what you want, but I'm not sure what that is. This code will create a new array where the elements are sum up by the 5% of the previews number.

let array = [1,2,3,4,5]
let percentage = 0.05 // 5%
let newArr = [1000]

array.forEach((element, i) => { 
  if(i > 0){
    newArr.push(newArr[i-1]   newArr[i-1] * percentage) 
  }
})

console.log(newArr)

If the numbers in array is irrelevant, so this may be enough. This will generate a new array with percentage base on index

let number = 1000
let array = [1, 2, 3, 4, 5]
let percentage = 5

const foo = array.reduce((acc, el, index) => {
    let result = number
    for (let i = 0; i < index   1; i  ) {
      result = (result / 100) * percentage   result
    }
    acc.push(Math.floor(result))
    return acc
}, [])

console.log(foo)
