Problem Statement

Inverted syntax with conditional expressions In traditional syntax conditional expressions are usually shown before the action within a statement or code block: In inverted syntax, the action is listed before the conditional expression in the statement or code block: Inverted syntax with assignment In traditional syntax, assignments are usually expressed with the variable appearing before the expression: In inverted syntax, the expression appears before the variable: Task The task is to demonstrate support for inverted syntax forms within the language by showing both the traditional and inverted forms.

Let's start with the solution:

alert "hello" if true
alert "hello again" unless false # the same as the above; unless is a negated if.

idx = 0
arr = (++idx while idx < 10) # arr is [1,2,3,4,5,6,7,8,9,10]

idx = 0
arr = (++idx until idx is 10) # same as above; until is an inverted while.
