This function converts one or more variables into a JSON encoded string. You can use this to store the data and then load it again using fromJSON.

string toJSON( var arguments ... )

arguments: A list of arguments of any type. Arguments that are elements will be stored as element IDs that are liable to change between sessions. As such, do not save elements across sessions as you will get unpredictable results.

Returns a JSON formatted string.

This example shows how you can encode an array. The string json should equal "["cat", "mouse", {cat:"hungry",mouse:"food"}]" after executed.

local json = toJSON ( "cat", "mouse", {cat="hungry",mouse="food"} )

-{{New feature|3|1.0|
-DP2 ignores the first argument, it starts generating the JSON string from the second argument and onwards. This is fixed in 1.0 and might cause compatibility problems in scripts using this function.
