The message is "at:put:". It's a single message send. I encourage you to try the ProfStef tutorial to understand the basis. On Oct 16, 2016 01:17, "CodeDmitry" <dimamakhnin@gmail.com> wrote:
I am trying to do a JavaScript experiment to make Objects behave like Smalltalk objects.
example:
"reminder: Smalltalk arrays start at 1." |arr| a := Array new: 1. a at: 1 put: 'Hello, World'.
Here, the Smalltalk array has a message "at: index put: value" which is defined many layers of prototype chaining down, at Object in category accessing.
However there are many messages on the way traversing the prototype chain that start with "at:", such as(SequenceableCollection) "at: x ifAbsent: y", "at: x incrementBy: y".
How does Smalltalk tell which message is which? Does it merge the messages into a single message such as "at: x put: y" to "atPut(x, y)" at some point?
Without knowing this, I have to traverse the whole call chain and check whether each argument is called in a specific way, which is incredibly expensive. If there was a single name such as "atPut" I can easily just do a dictionary lookup for this name and get it at O(1).
Does Smalltalk actually store each message?
