constant #49

Closed ShalokShalom closed 3 years ago

Hi there :)

Is there any chance to get a real, serious constant binding, that does what it says?

So deep freeze combined with casual const.

Thanks a lot

Edit: Seems like readonly does the job.

hello, i'm not sure what is wrong with const with prelude? seems the collections are immutable it should work?

undefined

Uncaught TypeError: Assignment to constant variable.

[ 1, 2, 3 ]
> vec1.append(4).toArray()
[ 1, 2, 3, 4 ]
> vec1.toArray()
[ 1, 2, 3 ]
