@ -5,7 +5,7 @@ Renders a tree view of a JSON object or array with collapsible content.
Use object destructuring to set defaults for certain props.
Use the value of the `toggled` prop to determine the initial state of the content (collapsed/expanded).
Use the `setState()` hook to create the `isToggled` state variable and give it the value of the `toggled` prop initially.
In the `render()` method, use a `<div>` to wrap the contents of the component and the `<span>` element, used to alter the component's `isToggled` state.
Return a `<div>` to wrap the contents of the component and the `<span>` element, used to alter the component's `isToggled` state.
Determine the appearance of the component, based on `isParentToggled`, `isToggled`, `name` and `Array.isArray()` on `data`.
For each child in `data`, determine if it is an object or array and recursively render a sub-tree.
Otherwise, render a `<p>` element with the appropriate style.
