Object Oriented Programming With Smalltalk - blocks, tests, loops and files

In this lesson, I explain: comparisons, tests, blocks, block arguments, methods to collect, select and reject elements from arrays and characters from strings, and also how to process text files with Smalltalk. As always, you should download a free copy of Squeak Smalltalk and a free copy of the Smalltalk/V Tutorials so that you can follow along with this course.

I can't thank you enough. Your insights are invaluable. Thank you soooo soooo much.

[@LearnWithHuw]

Thank you. That's very kind of you to say so.

[@josephliew4103]

Microsoft's odd PowerFx has odd similarities to smalltalk. I don't think it's coincidental that Microsoft's PowerApps editor has design similarities to squeak. Your video is making me think very hard what really is OOP today.

[@LearnWithHuw]

I've never used PowerFx. It wouldn't surprise me if Smalltalk has had an influence. Interesting.

[@josephliew4103]

Indeed. The parts of PowerFx that are similar to smalltalk are for communicating and interacting across the Microsoft 365 ecosytem. Even the loop implementation has similarities. I'm impressed by a modern Alan Kay's idea of messaging having an immediate relevance four decades since smalltalk was created.
Thank you for this excellent series. As a student struggling with OOP, it is very helpful. Perhaps the obession with teaching how to create objects works for the majority. But some of us just can't grasp OOP because we want to know how objects "talk" to each other. Thank you.
