Selection sort is a sorting algorithm that repeatedly scans an unsorted array and with each iteration finds the minimum element to build up a sorted array.

selectionSort.ts

function selectionSort(arr) {
  
  for(let i=0;i<arr.length;i++){
    
  for(let j=i+1;j<arr.length;j++){

    if(arr[i]>arr[j]){
      const temp=arr[i]
      arr[i]=arr[j]
      arr[j]=temp
    }
    
  }

  }

  return arr
  
}

selectionSort([9, 3, 6, 2, 1, 11]); // [1, 2, 3, 6, 9, 11]
selectionSort([12, 16, 14, 1, 2, 3]); // [1, 2, 3, 12, 14, 16]
