CSET-105 Intro to Web Applications

Week 2: Controlling the Flow of a Program

Main Objective: Learn the basic building blocks of all programming languages to solve simple algorithms.

Lessons:

1. Building Blocks of a Program
2. Review and discussion of Chapter 2
3. Syntax vs Style

Project:

The graded project this week is on problem solving using our basic building block algorithms. Go to the repl.it classroom and complete three Wk 2: Project Problems. Everyone must complete problem A and B, but you can choose which version of problem C you solve based on your level of comfort this week. Here is the grading breakdown for each problem:

• 6 points: Show the correct steps in comments
• 3 points: Produce the correct solution in code
• 1 point: Follow the style guidelines

Assessment:

Go to your cset repo on GitHub and create a new file in the 105 folder called assessment-2.md. Add your answers to the following questions to the file and "commit" them to GitHub. Here are the guidelines if you forget them.

• After two weeks, what do you think is going to be your biggest challenge with this program? And how will you try to overcome it?
• Describe the differences between the three styles of loops: for, while, and do...while.
• We've learned to split problem solving into two parts: writing the solution in English or pseudocode, then translating the solution into JavaScript. Why is this important and how will it help you in future classes?

Reference:

• MDN: Storing the information you need - Variables
• MDN: Making decisions in your code - Conditionals
• MDN: Loops and iteration

More Resources:

• Codecademy: Introduction to JavaScript
  • Interactive lessons to write and check code.
  • The first two lessons, "Introduction" and "Conditionals" will closely match this week's chapter.
  • They introduce "Functions," "Scope," and "Arrays" next. We haven't learned so don't worry about them yet. Although some parts of lesson six on "Loops" will rely on them.
• FreeCodeCamp: Introduction to JavaScript
  • More interactive lessons.
  • The lessons "Comment Your JavaScript Code" through "Understand String Immutability" will match this week's chapters. If you get to "Arrays," you're going beyond what we're learning.
  • This lesson uses an older version of JavaScript, so look at the first three lessons in their unit on ES6, the version of JS we're learning.
