Lecture 1: Introduction 목차 Abstraction (추상화) Programming languages are how we instruct machines to do our bidding The more precisely we can model domain-specific abstractions, the better programs we can write, i.e. - concise - maintainable - efficient - correct Abstraction is the process of generalizing concrete details to focus attention on details of greater importance.
