Typescript for change object properties name

Question

I have a problem about how to change object properties name. I have a object like this:

description: "Human Resource Management Module"

id: 8

route: "/apps"

__children: Array(2)

How can i change __children properties name to indexSearch?

Not really a typescript issue but an IDE one. Right click and "Rename" should do the trick ! — user4676340

I assume you are looking for solution to change object properties programmatically. you can assign the value of old property(__children) to a new one(indexSearch) and then delete the old property.

obj['indexSearch'] = obj['__children'];
delete obj['__children'];

see the below example.

var obj = {
  description: "Human Resource Management Module",
  id: 8,
  route: "/apps",
  __children: ['item1', 'item2']
};

console.log(obj)

obj['indexSearch'] = obj['__children'];
delete obj['__children'];

console.log(obj)

@Ozmen Typescript uses static types. You have to define the old and new fields first in your type declearation.

You can rename it like this, it's pretty simple:

You will have to use the keyboard, potentially the mouse as well.
