This video explains why you should JavaScript.

Understand what tools you need to start coding, in particular the console.

Overview of variables which are the the basic building blocks in programming. Learn how to declare them, and the difference between 'let' and 'const' keywords.

Introducing comments, which allow you to add explanatory notes to improve legibility of your code (and are ignored by the computer upon execution).

Learn how to use the console.log() built-in function to display data to the console.

FAQ: My console.log() is not working!
If console.log() in your browser does not work (i.e. it only returns 'undefined'), try the following:

1. Make sure you are in the 'User messages' tab (which is found on the left hand sidebar);

2. In the top bar, beside the 'Filter' searchbar, click on 'Default levels', and make sure 'Info' is checked. If the 'Default levels' is greyed out (i.e. unclickable), you'll need to hide/minimise the lefthand sidebar (by clicking on the button beside the 'Clear console' button);

3. If the above fail, then run this command in the console: console.log = (x) => {return x} . This should restore the console.log() function.

Overview of functions, which form the core of any program that you develop. Learn about the keywords 'function' and 'return', the differences between parameters and arguments, how are functions triggered, and how functions can work together to deliver complex functionality!

Learn how to install and use code editors (e.g. Sublime Text). This is the final lecture of Part 1.

A quick explanation of what you will be building in this part.

Overview of how websites/webpages are built (i.e. combination of HTML, CSS and JavaScript).

Learn how to inspect the HTML code of the CoinMarketCap website to formulate a strategy to retrieve the crypto price.

Overview of objects (as a programming concept) and the Document Object Model (DOM).

Practise your skills by converting your code into a function.

Learn how to use conditions (if/else statements) to add contigencies and logic to your code.

Learn a neat technique to insert placeholders into a string.

Oops, looks like we've encountered a problem in our code! Learn the steps and thought process to debug your errors.

Learn how to formulate your research queries to find the most relevant solutions efficiently.

We evaluate our progress and consider next steps for our project.

Overview of asynchronous programming (including the keywords 'async' and 'await') as we learn to implement a fetch() function to retrieve data from another webpage.

Learn about try and catch statements to handle errors in your code so your program does not crash during execution.

Learn how to invoke the fetchHTML() function, and understand what it truly returns.

Overview of promises, which is the return output of an asynchronous function. Learn how to 'resolve' these promises to access the actual output that you want.

Learn how to convert a standard JavaScript function into an arrow function, and implement that arrow function to resolve a promise.

Update the getPrice() function so that it accounts for newly inserted fetchHTML() function.

We evaluate again our progress and consider next steps for our project.

We sense an interesting pattern about the website URLs on the CoinMarketCap page...perhaps this is a clue for the next step?

Overview of arrays, which is a data structure to store multiple data types in one unit.

Overview of loops, which is a control flow technique to repeat a certain instruction for as many times as you specify. In particular, learn to apply the loop to work through items in an array.

Learn how to use objects for the purposes of storing data, and the advantages it has over an array in this case.

Learn how to access properties in an object, which is necessary to make this for loop work.

We go over our recent changes, test our code and....congratulations! You have built a functional JavaScript program in the broswer! We also consider next steps for Part Three.

Overview of the plan for Part Three

Overview of NodeJS, and how it relates to and supports JavaScript outside of the browser context.

Learn how to install and set up NodeJS.

Overview of dependencies/libraries and why we need them for this project. Also learn how to install dependencies through the node package manager (npm).

Learn what you need to do to use installed dependencies in your NodeJS program.

Learn how to run/execute NodeJS programs in your console.

Understand what changes you need to make whenever you rename a file in your NodeJS project.

We review our progress and consider next steps.

Introducing Twilio, which is a third party service that we'll rely on to send text messages to our phone. Here you will set up an account and familiarise yourself with the Twilio dashboard.

Overview of APIs (application programming interface) which allows you to leverage off third party services. Understand what you need to 'unlock' the API.

Learn how to install and use Twilio's dependencies in your NodeJS project.

Learn how to look up the documentation of Twilio and implement a sendMessage() function that can send texts to your phone.

Implement some additional final changes to tie the whole project together!

We're done! Now execute your code and watch your program send a crypto price alert to your phone!
