Hello. how to represent a tree as a flat array?

Answer 1

what is the question if the answer is in the tags? recursion
out id even ready, contain the identifier of the ancestor
stupidly run through all the branches of the tree, adding identifiers to the resulting array

function * flat(target) {
    yield target;
    if (target.children?.length) {
        for (const child of target.children) {
            yield * flat(child);
        }
    }
}
const target = {};
console.log([...flat(target)]); // Array.from(flat(target));

Answer 3

What kind of tree do you have there?
For example, if this is a balanced binary tree, then you can use the approach as here.
If something else, then you need to look at what exactly.
