script search by name with the union of similar serial numbers into a group

Question

Hi, I'm trying to write a script to search and merge layers and groups by matching sequence numbers, then merge the groups and set the group nameplayed with chatgpt, but since I have little knowledge in javascript, nothing works =((given:layers and groups named:"step_n_n""mask_n_n""back_n_n"n = sequence numbertask:group layers and groups with similar serial numbers and name the group "[slot] step-n-n" That's what chatgpt suggested &#128515;function findSimilarStepNums() {
  var stepLayers = app.activeDocument.layers;
  varstepNums = [];
  
  // Search for all layers with a name containing "step"
  for (var i = 0; i < stepLayers.length; i++) {
    if (stepLayers[i].name.indexOf("step") !== -1) {
      // Extract the number from the layer name and add it to the array
var num = parseInt(stepLayers[i].name.match(/\d+/)[0]);
      stepNums.push(num);
    }
  }
  
  // Search for duplicate numbers
  var similarNums = [];
  for (var j = 0; j < stepNums.length; j++) {
    for (var k = j + 1; k < stepNums.length; k++) {
      if (stepNums[j] === stepNums[k]) {
        similarNums.push(stepNums[j]);
        break;
}
    }
  }
  
  // Output found duplicate numbers
  if (similarNums.length > 0) {
    alert("Found similar sequence numbers for layers named 'step': " + similarNums.join(", "));
  } else {
    alert("Similar sequence numbers were not found for layers named 'step'.");
  }
  
  // Combining layers into a group and setting a name
var slotGroup = app.activeDocument.layerSets.add();
  slotGroup.name = "[slot] step-" + (stepNums.length + 1);
  for (var l = 0; l < stepLayers.length; l++) {
    if (stepLayers[l].name.indexOf("step") !== -1) {
      stepLayers[l].move(slotGroup, ElementPlacement.INSIDE);
    }
  }
}

cool, but I forgot about some nuances, sorry

Can you change this script so that it does not apply the action to the entire document, but only to the selected layers?...I think this will be the perfect way for the project 😃

// select layers the name of which ends in "_xx_xx";
// 2023, use it at your own risk;
if (app.documents.length > 0) {
// search layers with regexp;
var theLayers = collectLayersByNames([/_\d{1,2}_\d{1,2}$/], 2);
// process layers;
    if (theLayers.length > 0) {
        for (var d = 0; d < theLayers.length; d++) {
            selectLayerByID(theLayers[d][0][2], false);
            for (var e = 1; e < theLayers[d].length; e++) {
                selectLayerByID(theLayers[d][e][2], true)
                };
// group the active layer;
           groupSelectedLayers("[slot] step" + String(theLayers[d][0][0].match(/_\d{1,2}_\d{1,2}$/)).replace(/_/g, "-"));
            };
        } else {alert ("no such layer")}
    };

Quite frankly I think you may want to work on your manners.
