Obj iteration dynamically - javascript

help you fix your problem I have a json object, which needs to be iterated, I can make use of iteration as a function but wanted to see if there is a simpler way to do so. Object is as shown below: , You can split the string and then use reduce on the array of indexes:
code :
const arr = [
  {
    name: 'FolderA',
    child: [
      {
        name: 'FolderB',
        child: [
          {
            name: 'FolderC0',
            child: [],
          },
          {
            name: 'FolderC1',
            child: [],
          },
        ],
      },
    ],
  },
  {
    name: 'FolderM',
    child: [],
  },
];
const getObject = (arr, path) =>
  path
    .split('-')
    .reduce((result, key) => result.child[key], {
      child: arr,
    });

console.log(getObject(arr, '0-0-1'));

Does that help I'm trying to dynamically populate some optgroups for my select box in struts. The purpose is to group any duplicate names in the map that drives the select box control into their own option groups. , Just try the following code it may help you .
code :
    <s:select id="regionstate" name="state" list="stateMap">  
                 <s:iterator value="region" status="regionStatus">  
                     <optgroup label="%{name}">  
                             <s:iterator value="states" status="stateStatus">  
                                 <option value="%{id}"> %{name}</option>  
                             </s:iterator>  
                     </optgroup>  
               </s:iterator>
    </s:select>
Dynamically creating a new set for each iteration of a while loop

Dynamically creating a new set for each iteration of a while loop

wish of those help I would like to create a unique set for each iteration of a while loop. This while loop is nested inside of a for loop that does epoch conversions, etc., and creates a list that has the values associated with that particular entry in the list. , Why not use a, well ... Set
code :
from sets import Set
...
call_range_set = Set()
while call_start_epoch <= call_end_epoch:
    call_duration_two = call_start_epoch + 60
    call_start_epoch += 60
    call_range_set.add(call_duration_two)
...
In JavaScript, can you force a loop to not process the next iteration before the current iteration is complete?

seems to work fine If you want to handle it manually instead of relying on some kind of Promise implementation ( bluebird for example ) you can use this logic.
Overall looks more complicated, but apart the fact that should work, when you see and undertand this, adding your application knowledge you will be able to do something smaller, better.
code :
function addToCanvas(object) {
  canvas.add(object);
}

$(document).on("click", ".img-patt", function () {

   var imgURL = $(this).data("src");

   addSomething(imgUrl, null, null, addToCanvas)

});
function addSomething(imgUrl, index, objectStack, callback) {

        //this is where the process skips to the next iteration, before the image is loaded and added to the canvas

        fabric.Image.fromURL(imgURL, function (img) {

            //some code to handle the pattern removed from here just to shorten up the snippet

            var rect = new fabric.Rect({
                name: "texture",
                visible: true,
                selectable: false,
                data: {
                    type: $(_this).data("type"),
                    objid: $(_this).data("obj-id")
                },
                top: 0,
                left: 0,
                width: fabCanvas.width,
                height: fabCanvas.height,
                fill: pattern
            });

            objectStack && objectStack[index] = rect;
            callback(rect)
          });
}
$.ajax({
    url: url,
    method: "GET"
}).done(function (data) {
    var objectStack = new Array(data.length);
    var loaded = data.length;
    var onFinish = function() {
      loaded--
      if (loaded === 0) {
        objectStack.forEach(function(object) {
          canvas.add(object);
        });
      }
    }
    data.forEach(function (data, index) {
        var src = $('img[data-obj-id="' + data.object_id + '"]').data('src');
        switch (data.layer_type) {
            case "texture":
                {
                    addSomething(src, index, objectStack, onFinish)
                    break;
                }
            case "color":
                {
                   ...
                }
            case "room":
                {
                    ...
                }
            case "decor":
                {
                   ...
                }
            case "floor":
                {
                    ...
                }
            default:
                {
                    ...
                }
        }
    });

This might help you If I understand correctly, each comment can have 0 to n replies, which are also comments that can have 0 to n replies, and so forth.
So you need a recursive function that is called for each comment, regardless of its depth relative to the original posting, but keeps track of that depth.
