Wish Root variable conflict in JSON Tree Example

[Lucas Siqueira]

when working with b4xpages there is already a declared root variable.
it always conflicts when we convert the code in the JSON Tree Example

https://b4x.com:51041/json/index.html

Change:
M if it is Map
L if it is List

Dim parser As JSONParser
parser.Initialize(<text>)
Dim root As Map = parser.NextObject
Dim token As String = root.Get("token")

Update to:

Dim parser As JSONParser
parser.Initialize(<text>)
Dim m As Map = parser.NextObject
Dim token As String = m.Get("token")

or use (AS)

    Dim sText As String = $"{"token":"NTE3NzUzZmU3Yjk4ZDdjMmQ1YmQ0MzZjYzE0NThmMzBiNDhhZTBjOGJiMmUwYmU3MTY0MDM4NTAwOA=="}"$
    Log(sText.As(JSON).ToMap.Get("token"))
    Log(sText.As(JSON).ToMap.As(JSON).ToString)

There is no conflict, just a personal preference. You can change the generated variable name to whatever you like with Replace All command.

sorry, but what I want to propose is to get it fixed, especially for new users, who have a hard time idenfying why the code went wrong.

i know i can use this .AS(Type) option, i always fix the code i copy there from json. I don't have a problem with that myself.

but teaching b4xpages to new users, they get confused in using the feature, because it's not just copy and put, you have to modify

There's absolutely nothing to fix here. Just chance the variable name, it takes a few seconds to do...
