How to sort only number values in array?

Question

var points = [2, a, t, 5, 4, 3]; and after sort: var points = [2, a, t, 3, 4, 5];

Any help about that? it is possible to post your help with old style javascript code because i work on Adobe DC project?

my code is there :

var points = [t1, t2, t3, t4];
[t1, t2, t3, t4] = points;

var lucky = points.filter(function(number) {
  return isNaN(number) == false && number !=="" && number!== undefined;
});
points=lucky
points.sort(function(a, b){return a - b});

this.getField("Text6").value = points

but this only sort min to max and filter other characters... i need to keep other characters and short only numbers...

Answer 1

var points = [2, "a", "t", 5, 4, 11, "", 3];
var insert = points.slice(0); // Clone points

// Remove all elements not a number
points = points.filter(function(element) {
  return typeof element === 'number';
});

// Sort the array with only numbers
points.sort(function(a, b) {
  return a - b;
});

// Re-insert all non-number elements
insert.forEach(function(element, index) {
  if (typeof element !== 'number') {
    points.splice(index, 0, element);
  }
});

console.log(points);

You may be able to do this more efficiently by avoiding splice() if you simply reassign the values in place.

Filter, sort, the reassign to sort the numbers in place:

let arr = ['c', 2, 'a', 't', 5, 4, 3, 'b', 1]

let n = arr.filter(c => typeof c == "number").sort((a, b) => a-b)
for (let i = 0, c=0; i<arr.length; i++){
    if (typeof arr[i] == "number") arr[i] = n[c++]
}
console.log(arr)
