my obj looks like that:
blogPost: {
questions:
[
{
id: 234
}
]
}
I would like to destructure id, but this doesn’t seem correct.
const {questions[0]: {id}} = blogPost

Use array destructuring as well to make it work:
{questions:[{id}]}=blogPost
Alternatively, you can use object destructuring on arrays as well (arrays are objects), but that is less semantical:
{questions:{'0':{id}}}=blogPost
That accesses the property in a different way: array destructuring calls Symbol.iterator method to iterate over the array, while object destructuring does a [[Get]] operation on the specified keys only.

interesting! I didn't know it was possible to destructure a nested object. With the above operation you also declared a variable named "questions", or just the "id" one?
Try this:
const { questions } = blogPost;
const { id } = questions[0];
