How to generate object/array

The editor uses eval(<input-value>). 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 ({}),([])
How the editor works

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.

Edit keyboard shortcuts

When element is editable:

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