Why is split: implemented in the separator rather than the string?

369 posts

I keep getting this wrong, which makes me wonder why we send split: to the separator rather than the thing to be split. Is there a benefit to doing

$- split: '1969-07-20'

rather than

'1969-07-20' split: $- (which somehow seems more natural to me).

Cheers

Because you are telling the receiver that he should split the argument.

"Hey dash, can you split this for me?"

rather than

'1969-07-20' split: $- (which somehow seems more natural to me).

Try instead '1969-07-20' splitOn: $-

"Hey collection, can you split on this?"

If you want to do it reversed, do it like this:

'1969-07-20' splitOn: '-'
