   "i": 25
   "j": 50
   
   if $"i" == 25 ??
       echo "Hello World!" /echo
       if $"j"/2 == $"i" ??
           echo "Hello World!" /echo
       /if
   /if

   Or:

   "i": 1
   if $"i" == 1 ?? ;; echo "Hello World!" /echo ;; /if

4. Loops

   "text": "Hello World!"
   
   loop $"i" != $"text".len ??
       echo $"text"[$"i"] /echo
       "i": $"i"++
   /loop

   Or:

   "i": 0
   "text": "Hello World!"
   loop $"i" != $"text".len ?? ;; echo $"text"[$"i"] /echo ;; "i": $"i"++ ;; /loop

5. Functions

   function add ?? "add.1", "add.2"
      "add.result": $"add.1" + $"add.2"
      return $"add.result" /return
   /function
      
   "example_function_call": add 1, 2 /add
   echo $"example_function_call" /echo

   echo add 1, 2 /add /echo

6. Type checking for a string returns "string" for a number returns "number" for an array returns "array"

   "2": 10.5
   "3": "Hello World!"
