Structurally, objects are nothing more than a set of partially applied, cohesive functions. And thinking in objects should (perhaps) not start with writing the “class” keyword.
In this video, Alex is offering an alternate perspective to the common “class-oriented development” used in many of the modern programming languages. This perspective is not meant to be used in production, only to be understood since the “objects first” perspective leads to better designs.
Happy learning!
