JavaScript Fundamentals - Part 1

Today we will be learning the fundamentals of JavaScript!

✋ Pre-lecture work

This workshop includes some reading and exercises that should be done prior to attending the lecture.

Read all of the .md files in __pre-lecture-work. It covers the initial fundamental concepts that we will be starting with during the lecture.

There are also some exercises that you should complete.

Workshop Setup

Before starting the workshop, please run the following in the terminal. It will install all of the required dependencies. (More on that later.)

Type ctrl+ j to open the terminal inside of VS Code.

yarn install

In order to more easily evaluate your answers, you will need a node environment. VS Code provides us with a terminal, and in the terminal we can evaluate js files with Node.

It really NOT recommended that you use the browser console.

You can toggle the terminal window in VS Code with the following keyboard shortcut:

[ctrl + j] on Windows
[cmd + j] on Mac

This will open an instance of the terminal (Mac) or the PowerShell (Win).

Type JS directly into the Node Env.

Type node in the terminal, and hit enter.

This will turn that terminal into a Node environment for you to play with.

You can type JavaScript in the same way I did while using the web browser console.

You can also copy/paste your code from your file into the node environment.

Exit the Node Environment

To exit/quit Node and get back to the terminal, do [ctrl + c] twice.

Testing

This workshop can "test" your code and validate your answers. (We will talk more about this later.)

If you want to test your code/validate your answer, you can type yarn test <FILE_NAME> in the terminal (without the .js).

In this workshop, there will be a reminder to do this at the end of every exercise file.

The Workshop

Each question is a JS file, except for the exercise-2.md. The question, including guidelines and hints, are also located each exercise file.

These first exercises are heavily commented. In order to implement unit tests and allow you to verify your own code, each file contains extra lines of code that are not related to the actual exercise. These lines should not be modified at all.

Exercise 1

This is a series of theory questions for you to answer. - Open exercise-1.js and answer in the file.

Write your answer inside of the provided console.log().

// Example
console.log("1.1. ( )"); /* "I am a "Horse""    */

Exercise 2

This a series of code jumble questions. Answer directly in the exercise-2.md file.

There is no automated testing for this file.

For exercises 3 to 13, you should only write the needed code to solve the exercise between the provided lines.
