Ajsone

Ajsone is an esoteric programming language created by Alok Menghrajani. The language abuses JSON by using the JSON data format to represent everything: functions, variables, values, etc.

Examples
The following computes the factorial of 5.

{   "fact": { "=if": { "cond": {"=<=": {"in1": "=n", "in2": 1}}, "then": 1, "else": { "t": {"=-": {"in1": "=n", "in2": 1}}, "=*": {"in1": "=n", "in2": {"=fact": {"n": "=t"}}}} }   },    "=fact": {"n": 5} }
