addValueByPath<T>(
    value: T,
    path: string,
    node?: LabelledNode<T>,
    pathOpts?: Partial<
        Readonly<
            { duplicates: "ignore"
            | "allow"
            | "overwrite"; separator: string },
        >,

Adds a value by a string path, with '.' as a the default delimiter Automatically generates intermediate nodes.

```
