In ts file:

    sample = {
        "data": [
            {
                "name": "Azad University",
                "tedad": 80
            },
            {
                "name": "University of Science and Technology",
                "tedad": 14
            },
            {
                "name": "University of Kurdistan",
                "tedad": 30
            }
        ]
    }
constructor(){
    this.sample.data.sort(function(first, second) {
                return (first.tedad - second.tedad);
            });
            console.log(this.sample);
}

parameters in Array.prototype.sort() are elements of the array. You can access by property of theirs.

const items = {
  "data": [{
      "name": "Azad University",
      "tedad": 80
    },
    {
      "name": "University of Science and Technology",
      "tedad": 14
    },
    {
      "name": "University of Kurdistan",
      "tedad": 30
    }
  ]
}

const sorted = items.data.sort((prev, curr) => prev.tedad - curr.tedad);

console.log(sorted)
