How to save String prompt input into an array

Question

Thank you all for you effort. Everything works fine.

Answer 1

Here is an example.

This will take the two numbers given and populate the array from smallest to largest.

You can can then decide how to handle the array after that.

let arr = [];                    //create array

let numOne = validateNumber();
let numTwo = validateNumber();
createArray(numOne, numTwo);     // call function to populate array

arr.forEach(number => {
  console.log(number);
})              


function validateNumber(){
  let pass = false;
  let number = 0;
  while (!pass){
    number = parseInt(prompt('Enter a number'));
    if (Number.isInteger(number)) pass = true;
  }
  return number;

}

function createArray(numOne, numTwo){
  var start = numOne;
  var end = numTwo;

  if (numOne > numTwo){
    start = numTwo;
    end = numOne;
  }
  for (var i = start; i <= end; i++) {
    arr.push(i)
  }
}

Answer 2

You could create a function like the one below to get started.

function returnRange(start, end) {
    //Array to store numbers in.
    var myarray = [];

    // Check if the provided parameters are numbers and return an error message if they are.
    // Else add the range of numbers to the array
    if (isNaN(start) || isNaN(end)) {
        console.log("One of these is not a number:");
        console.log("start = " + start + " end = " + end);
    } else {
        //Loop through your input and store into an array
        for (var i = start; i < end + 1; i++) {
            myarray.push(i);
        }

        // You can use console.log(myarray) here to verify it is returning the correct range
        return myarray;
    }
}

returnRange(1,5);
