Introduction

# Course Review: Programming Languages, Part A on Coursera ## Overview If you're looking to deepen your understanding of programming languages and enhance your coding skills across various paradigms, I highly recommend the "Programming Languages, Part A" course offered on Coursera. This course serves as an introduction to the fundamental concepts of programming languages, with a particular focus on functional programming. Utilizing languages such as ML, Racket, and Ruby, the course aims to equip learners with a robust conceptual framework that makes it easier to understand and work with any programming language. ### Course Goals The main intent of this course is not merely to teach specific programming languages but to provide insights into how different languages "fit together." The course fosters an environment where participants can become proficient in their existing programming language of choice while simultaneously gaining the skills necessary to learn new languages effectively. ## Course Syllabus Breakdown ### 1. Introduction and Course-Wide Information The journey begins here! This introductory module gives you a clear understanding of the course layout and expectations. The welcome message sets a friendly tone, assuring students that they are in for an engaging journey into the world of programming languages. ### 2. Software Installation and Homework 0 Before you can dive into the programming concepts, you need to install specific software essential for the course. This module provides comprehensive guidance on the installation process. There’s also an optional, introductory homework assignment that allows you to familiarize yourself with the course's submission and peer assessment mechanics. ### 3. Section 1 and Homework 1 This section marks the beginning of your deep dive into functional programming. Following a careful reading of the introductory message, you get to explore core concepts while tackling your first actual homework assignment, which sets the stage for more complex ideas to come. ### 4. Section 2 and Homework 2 This module is particularly illuminating, revealing the elegant structure underlying ML (Meta Language). You'll find this section rewarding as you connect the dots between different programming principles. Dedicate ample time to the programming assignment; it requires a methodical approach to grasp the intricate ideas presented. ### 5. Section 3 and Homework 3 – Additionally, Course Motivation Here, you will encounter higher-order functions, a fundamental concept in functional programming that significantly enhances its expressiveness. An essential part of this section is the "course motivation" lesson, which, while optional, is highly recommended for a broader perspective on the course's overarching goals and its relevance to your programming journey. ### 6. Section 4 and Part-A Exam The course culminates with an examination that encompasses all the content covered in Part A. This module introduces essential concepts like type inference and ML's module system, allowing you to solidify your understanding before moving on to the subsequent parts of the course. A wrap-up video provides insights into what you can expect from Parts B and C, keeping the momentum going. ## Strengths of the Course - **Comprehensive Framework**: The course offers a well-rounded view of programming languages, providing learners with a structure that transcends specific languages. - **Hands-On Learning**: With practical homework assignments at the end of each section, you will gain invaluable hands-on experience. - **Expert Instructors**: The course is designed and presented by knowledgeable instructors who effectively communicate complex concepts in an accessible manner. - **Engaging Content**: The combination of video lectures, readings, and interactive assignments keeps the learning experience engaging and diverse. ## Recommendations This course is particularly well-suited for: - **Beginners**: Those new to programming will find a solid foundation in the basic concepts of various programming paradigms. - **Intermediate Programmers**: For those with some experience, the course provides a deeper understanding of how programming languages function, particularly in functional programming. - **Lifelong Learners**: If you’re interested in broadening your programming knowledge and improving your adaptability in learning new languages, this course is for you. In conclusion, “Programming Languages, Part A” on Coursera offers a unique opportunity to explore the world of programming languages through a structured, engaging, and practical approach. Whether you aim to become a more versatile programmer or are simply curious about the intricacies of programming languages, this course is a brilliant investment in your coding education. I wholeheartedly recommend enrolling and embarking on this enlightening journey!

Syllabus

Introduction and Course-Wide Information (Start Here)

Welcome! Start here! Learn about this course and how it's organized.

This module contains two things: (1) The information for the [unusual] software you need to install for Programming Languages Part A. (2) An optional "fake" homework that you can turn in for auto-grading and peer assessment to get used to the mechanics of assignment turn-in that we will use throughout the course. You can do this module either before or after watching the first few "actual course content" videos in the next module, but you will want to get the software installed soon so you can learn by actively trying out variations on the code in the videos. You will need to install the software to do the homework.

It's time to dive in! Start with a careful reading of the "Section 1 Welcome Message" and go from there.

This section is a particularly rewarding one where a lot of ideas come together to reveal a surprisingly elegant underlying structure in ML. As usual, start with the welcome reading, dive into the material, and leave plenty of time to approach the programming assignment methodically.

This section is all about higher-order functions -- the feature that gives functional programming much of its expressiveness and elegance -- and its name! As usual, the first reading below introduces you to the section, but it will make more sense once you dive in to the lectures. Also be sure not to miss the material on course motivation that we have put in a "lesson" between the other videos for this week and the homework assignment. The material is "optional" in the sense that it is not needed for the homeworks or next week's exam, but it is still very highly encouraged to better understand why the course (including Parts B and C) covers what it does and, hopefully, will change the way you look at software forever.

We finish Part A of the course with this module. As explained in more detail in the welcome message, we discuss type inference, ML's module system, and the fundamental idea in computing of two computations being equivalent. There is no programming assignment -- instead there is an exam covering all of Part A. Finally, there is a brief wrap-up video for the end of Part A that also looks ahead to Part B and Part C -- we have put it after the exam, so don't overlook it.
