      integerVar = 4 + 6 + YOLO
      print integerVar

  52.0

• Strings, strings operations : =* (concat)

      stringVar = "yo" * 3

• Comments : singleline // , multiline /* */

• Loop control : continue & break

• for \ while \ do-while loops

      for (i = 0 : i < 10 : i = i + 2) {
          print "i = " + i
          if i == 4
              стопэ
          print ", "
      }

  i = 0.0, i = 2.0, i = 4.0

• System functions : sin, cos, fancyPrint ...

      fancyPrint(1, 2, 3, 4, 5, YOLO)

• User defined functions : fun

      fun sum(a, b) {
          a = a + 4
          fancyPrint(a, " ", b, "\n")
          return a + b
      }
  
      a = 1
      print sum(a, 2)

Program Demo

Code Example:

    /*
        Example
        of
        multiline
        comment
    */

    arr = [1, "text", 1+1, [2 + 3]]
    print arr + "\n"
    arr[0] = arr[0] + 1000 + arr[1]

    fun println(i) {
        print "i = " + i + "\n"
    }

    // So work strings
    word = "yay " + "nice"
    drücke word + "\n"

    // So work numbers
    yo = 5.5 * 2 - 1 + YOLO
    print yo
    print "\n"

    // So work conditionals
    if (40 > 50) || (50 != 60) {
        печать "true\n"
        print "true1\n"
    }
    altfel {
        afișează "false\n"

        i = 0
        while (i < 10) {
            print "i = " + i + "\n"
            i = i + 1
            if i == 4
                oprește
        }
        for (i = 0 : i < 10 : i = i + 2) {
            print "i = " + i + "\n"
            if i == 4
                continue
        }

        do {
            println(i)
            i = i - 1
        } while (i >= 0)
    }
