About editing nodes

When editing a node value, the JSON value type is determined based on the value. For example, after inputed 10.5 and saving the JSON to a file, it will be output as a float type 10.5. If the value sorround with ", it will be output as string type always. The following is a list of conversion rules.

input value	json type
`gorilla`	string
`10.5`	float
`5`	int
`true` or `false`	boolean
`null`	null
`"10"` or `"true"`	string

About adding new node

You can use a to add new node with raw json string.

For expample, you have following tree.

{array} <- your cursor in there
├──a
├──b
└──c

If you input {"name":"gorilla"} and press add button, then you will get new tree as following.

{array} <- your cursor in there
├──a
├──b
├──c
└──{object}
   └──name
      └──gorilla

Also, You can use A to add new value to current node.

For example, you have following tree.

{object} <- your cursor in there
└──name
   └──gorilla

If you input {"age": 26} and press add button, then you will get new tree as following.

{object} <- your cursor in there
├──name
│  └──gorilla
└──age
   └──26
