providing text responses rather than numerical values

Question

providing text responses rather than numerical values

I am currently working on developing a function called onlyOddNumbers that takes an array of numbers as input and outputs a new array with only the odd numbers. The function is operational, but I have encountered an issue where strings are being included in the new array instead of just numbers. Can someone explain why this is happening?

let oddNumbersOnly=[]
const filter = function (numbers) {
  for (number in numbers){
    if(number %2 !==0){
      oddNumbersOnly.push(number)
    }
  } return oddNumbersOnly;
};

Answer №1

Instead of using a for loop, try utilizing the for...of loop and remember to convert your number into a string.

const filter = function(numbers) {
  let oddNumbersOnly = []
  for (let number of numbers) {
    if (number % 2 !== 0) {
      oddNumbersOnly.push(number.toString())
    }
  }
  return oddNumbersOnly;
};
const arr = [1, 2, 3, 4, 5, 6];
const result = filter(arr)
console.log(result)
