For Loop Jade

[timrijckaert]

Hi

I noticed the for loop doesn't seem to be working.
When the following code is run
(as seen on CodePen)

body
    - for (var x = 1; x < 16; x++)
    .div= x

I get :

Uncaught Exception ::unable to evaluate [for (var x = 1; x < 16; x++)] - Parsing de.neuland.jade4j.expression.ExpressionHandler.evaluateExpression@1:12 parsing error near '... r x = 1; x ...'
