Dynamically increment number when it reaches a dynamic input

I want to increment only when index passes the condition. Array length is dynamic. input_number is dynamic.

let increment = 0  let input_number = 4    array.forEach((arr, index) => {    // increment++ when index > 4 && index <= 8    // increment++ when index > 8 && index <= 12    // increment++ when index > 12 && index <= 16    // so on...  })      let increment = 0  let input_number = 3    array.forEach((arr, index) => {    // increment++ when index > 3 && index <= 6    // increment++ when index > 6 && index <= 9    // increment++ when index > 9 && index <= 12    // so on...  })
