You need to give complete path when you have to destrcuture a nested property.
const obj = {
d: {
results: {
__metadata: [Object],
ObjectID: '00163E6CDDFC1EEA96C57123A5C6DDE5',
InformationLifeCycleStatusCode: 'AC',
ID: '9000001424'
}
}
}
const {d : {results : {ObjectID}}} = obj;
console.log(ObjectID)

The only thing you forgot to mention is if you try to destructure a nested object and it doesnt exist, you get an error instead of just cascading to undefined. More on reddit.com
Syntax for type annotations when making an array destructuring assignment within a for...of loop.
I run into this quite a lot. Unfortunately, there is no existing TS syntax that allows you to type destructured variables inline. An alternative to your solution is to cast the type of the entries themselves ahead of time: const unitEntries = Object.entries(myUnits) as [Units, number][] for (const [key, value] of unitEntries) { testKey(key); } Updated TS Playground This is a little more verbose, but it has the benefit that if you are going to reference those variables anywhere else in or outside the loop, you won't have to cast them again. Also, let me know if you create or find an existing feature request on TypeScript's GitHub. I will totally +1 it :-) More on reddit.com

This is also working for deeper nested properties, just repeat the destructuring syntax using colons. The innermost of the destructuring will be available as local variables. Also you can of course destructure a list of properties, like so… · const writeAddressDetails = ({ address: { details: { street, number } } }) => { console.log(street); console.log(number); } writeAddressDetails(person); // Broadway // 3155 · BTW: this is an official JavaScript feature also included in the JavaScript documentation for object destructuring.

How to Destructure Nested JavaScript Objects | by Jay Cruz | JavaScript in Plain English
October 24, 2021 - Here we have our employees object nested several levels deep. If we need to access an employee’s info we can destructure as many levels as it takes to get to our employee object’s properties. Now we have access to all of the second employee object’s properties. Destructuring is a very useful feature that was added to the ES6 version of JavaScript.

The first destructuring creates only Start and End variables. If you want to create current as a variable, then you need to declare it again.
function ({ current: { selectionStart: Start, selectionEnd: End }, current }, AppStateSetter) {
// do something with current , Start , and End
}
You can test it on the Babel compiler:
This code:
const object = {
current: {
selectionStart: "prop 1",
selectionEnd: "prop2"
}
}
const { current: { selectionStart: Start, selectionEnd: End } } = object;
Gets trasnpiled to:
var object = {
current: {
selectionStart: "prop 1",
selectionEnd: "prop2"
}
};
var _object$current = object.current,
Start = _object$current.selectionStart,
End = _object$current.selectionEnd;
As you can see, current variable is not created.

I think the issue you are facing happens when current is undefined.
You can try destructing with default value.
function ({ current: { selectionStart: Start, selectionEnd: End } = {} }, AppStateSetter) {
// do something with Start and End
}
If you think you need to access current as well, try destructuring inside the function.
function ({ current = {}}, AppStateSetter) {
const { selectionStart: Start, selectionEnd: End } = current
// do something with current, Start and End
}
