How do you find all pairs of an integer array whose sum is equal to a given number in javascript or typescript

You must have seen this question in many of the interviews related to programming. This can be implemented in any language and using so many approaches. The solution I suggest is:

const findAllPairsOfAnIntegerArrayWhoseSumIsEqualToAGivenNumber = (arr, targetSum) => {
 const pairs = [];
  for(let i = 0; i< arr.length; i++) {
    for(let j = i+1;  j < arr.length; j++) {
      if(targetSum == arr[i] + arr[j]) {
          console.log(`The sum of ${arr[i]} and ${arr[j]} is ${targetSum}`)
 return pairs

And this is how you call it:

findAllPairsOfAnIntegerArrayWhoseSumIsEqualToAGivenNumber([0,1,2,3,4,5,6,7,8,9], 10)
