Array with different data types in a JSON object

Hi all,

Do you know how to include in a JSON object (new framework) an array that contains different data types (string, integer…)? Like here:

var myData = { "types": [ ["city", 120000], ["roads", 250] ], "data": [ [1,1,"Juillet 2015","AB5"], [1,2,"","AC65"] ] };

Thank you

Make the arrays of type Auto.

Thank you Kem!
