MiniScript supports if/else-if/else, with arbitrary number of else-if sections when in block form: |
|||
<lang MiniScript>x = 42 |
|||
if x < 10 then |
|||
print "small" |
|||
else if x < 20 then |
|||
print "small-ish" |
|||
else if x > 100 then |
|||
print "large" |
|||
else |
|||
print "just right" |
|||
end if</lang> |
|||
It also supports single-line if or if/else statements (though no else-if sections are permitted in this case): |
|||
<lang MiniScript>x = 42 |
|||
if x < 50 then print "small" else print "big"</lang> |
|||
Finally, like many other languages, MiniScript uses short-circuit evaluation, a form of implicit branching where the rest of a boolean expression is not evaluated at all if the truth value can already be determined. |
|||
<lang MiniScript>isSmall = function(x) |
|||
print "checking smallness" |
|||
return x < 40 |
|||
end function |
|||
isBig = function(x) |
|||
print "checking bigness" |
|||
return x > 60 |
|||
end function |
|||
isSmall(10) or isBig(100)</lang> |
|||
{{out}} |
|||
<pre>checking smallness</pre> |
