Software Installation and Homework 0

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.

Section 2 and Homework 2

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.

Section 3 and Homework 3 -- and Course Motivation

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.

Top reviews from Programming Languages, Part A

By YZDec 3rd 2016

I'm just a beginner for CS or SE classes, and find this course really concise and challenging. It opens a door for me to get deeper into programming language. No wonder it got so high average score.

By ALMar 22nd 2017

Great course!\n\nI think this course has just the right balance of theoretical background, formal definitions, and actual examples to make "just right".\n\nThanks Dan, and everybody else involved!
