• Kinglish: Does this answer your question? How can I remove a specific item from an array?

Answer 1

You can do this simply with the delete operator which removes a property from an object. In this case, you can use:

delete regions.regions[0].Shops;

Answer 2

Use delete to get rid of an object, or maybe multiple if you wanted to.

"regions": [
 {
 "Id": 1,
 "code": 1,
 "name": "Trivandrum",
 "Categories": [
 {
 "Id": 1,
 "category_id": 1,
 "region_id": 1,
 "ref_count": 2,
 }
 ],
 "Shops": [
 {
 "Id": 33,
 "is_enabled": true,
 "is_setup_complete": false,
 "approval_time": 10,
 "packaging_time": 30,
 "erp_ref": "45645655",
 "priority": 0,
 "admin_id": 11,
 "region_id": 1,
 },
 {
 "Id": 34,
 "is_enabled": true,
 "is_setup_complete": false,
 "approval_time": 10,
 "packaging_time": 30,
 "erp_ref": "4524645",
 "priority": 0,
 "admin_id": 11,
 "region_id": 1,
 },
 
 ]
 }
 ]
delete(region.Shops);
console.log(region);

let regions = [

 "code": 1,
 "name": "Trivandrum",
 "Categories": [
 {
 "Id": 1,
 "category_id": 1,
 "region_id": 1,
 "ref_count": 2,
 }
 ],
 "Shops": [
 {
 "Id": 33,
 "is_enabled": true,
 "is_setup_complete": false,
 "approval_time": 10,
 "packaging_time": 30,
 "erp_ref": "45645655",
 "priority": 0,
 "admin_id": 11,
 "region_id": 1,
 },
 {
 "Id": 34,
 "is_enabled": true,
 "is_setup_complete": false,
 "approval_time": 10,
 "packaging_time": 30,
 "erp_ref": "4524645",
