`ts
;(params: {
node: Record | Array // Object or array
indexOrName: number | string | undefined
depth: number
size: number // Object's size or array's length
}) => boolean
`

$3

`ts
{
add?: boolean
edit?: boolean
delete?: boolean
}
`

> onEdit, OnDelete, onAdd and OnChange add parentPath field, allow us to correctly indicate which field in the JSON is being edited.

$3

`ts
(params: { node: any; indexOrName: number | string | undefined; depth: number }) =>
| {
add?: boolean
edit?: boolean
delete?: boolean
enableClipboard?: boolean
collapsed?: boolean
className?: string
}
| React.FC
| typeof React.Component
| React.ReactElement
`

$3

`ts
{ depth: number; indexOrName?: number | string; parent?: Record | Array; parentPath: string[], currentPath: string[] }
`

Editable

$3

The editor uses JSON.parse(). While in edit mode, you can enter ({}) or ([]), which will cause the result of eval to become a new object or array.

> {} and [] will be auto convert to ({}),([])

$3

This component does not perform any cloning operations, so every step of the operation is carried out on the original object. If cloning is required, please handle it yourself.

$3

When element is editable:

- Ctrl/Cmd+Click => Edit Mode
- Enter => Submit
- Esc => Cancel
