Example of removing duplicate json from an array in JS

This article illustrates a method to remove duplicate JSON objects from an array in JavaScript. Shared for everyone's reference, the details are as follows:

var array = [{"name":"123},{"name":"123},{"name":"456}]
unique(array);
function unique(list) {
  var arr = [];
  for (var i = 0; i < list.length; i++) {
    if (i == 0) arr.push(list[i]);
    b = false;
    if (arr.length > 0 && i > 0) {
      for (var j = 0; j < arr.length; j++) {
        if (arr[j].typesname == list[i].typesname) {
          b = true;
          //break;
        }
      }
      if (!b) {
        arr.push(list[i]);
      }
    }
  }
  return arr;
}
