Set nested path on self during declaration creation in JavaScript-CodePudding

just wondering if anyone knows of a good way to declare an object with a nested path that also is using spread syntax.

Here is an example that I know works:

const copyMe = {
    name: 'mike',
    id: '123abc456def',
    nested: {
        path: 'the old value'
    }
}

const newObject = {
    ...copyMe,
}

// Works, but adds an extra line of code.
newObject.nested.path = 'the new value'

console.log(newObject) // newObject.nested.path = 'the new value'

However I would like to do something like this, where I copy an entire object using spread syntax, and in the same declaration overwrite/create a path & set its value.

const copyMe = {
    name: 'mike',
    id: '123abc456def',
    nested: {
        path: 'the old value'
    }
}

// Syntax is incorrect. Example of what I wish to accomplish.
const newObject = {
    ...copyMe,
    ...copyMe.nested.path: 'new value here'
}

Thanks!

}

const newObject = {
    ...copyMe,
    nested: { ...copyMe.nested }
}

const copyMe = {
    name: 'mike',
    id: '123abc456def',
    nested: {
        path: 'the old value'
    }
}

const newObject = {
    ...copyMe,
    nested: {
      path: 'new value here'
    }
