Creating Json is easy with play framework / scala. here is an example about it ,
import play.api.libs.json.Json
val json: JsValue = Json.parse("""
{
"user": {
"name" : "toto",
"age" : 25,
"email" : "[email protected]",
"isAlive" : true,
"friend" : {
"name" : "tata",
"age" : 20,
"email" : "[email protected]"
}
}
}
""")

I guess you just want an array, not an object:
Json.arr(
Json.obj(
"id" -> "node37",
"name" -> 3.7,
"data" -> Json.obj(),
"children" -> Json.arr()
),
Json.obj(
"id" -> "node38",
"name" -> 3.8,
"data" -> Json.obj(),
"children" -> Json.arr()
)
)
Which gives
[{
"id": "node37",
"name": "3.7",
"data": {},
"children":[]
},
{
"id": "node38",
"name": "3.8",
"data": {},
"children":[]
}]
JSON.parse() in the browser? Still it is possible to declare such an object in JS: var foo = {"id": 1234}
