What is JavaScript From Zero: Make Web Pages Come Alive?

Learn the core of JavaScript by building one small app, a task list that adds, filters, saves and loads data, with a built-in check after every exercise. You start with an HTML page that cannot react. You finish with a working task list app that you built, tested and reviewed yourself: it adds, marks, deletes and filters tasks, saves them in the browser, loads sample data from the internet and proves itself with automatic checks every time it opens. You will understand each part well enough to start a second app on your own.

People who can write basic HTML (headings, paragraphs, lists, buttons and a simple form) and want their pages to react to clicks, forms and live data. No programming experience is needed.

These are the prerequisites the course lists:

• Basic HTML: you can make an .html file with headings, paragraphs, lists, buttons and a form with a text box, and open it in a browser
• You can create folders and save plain text files on your computer
• No prior programming and no CSS knowledge are needed; the style sheet you need is given to you

These are the tools and materials the course lists:

• A computer (Windows, Mac or Linux) and a current desktop web browser such as Chrome, Edge, Firefox or Safari. The steps name Chrome shortcuts. Other browsers have similar developer tools under similar menu names, so look for Developer tools or Inspect if your screen looks different
• A plain text editor. Notepad or TextEdit in plain text mode works. A free code editor such as Visual Studio Code is more comfortable; check its current download page
• A folder on your computer called task-list, where you will keep every file of the project
• An internet connection for Lesson 6.2 and for looking things up. Every other lesson works offline
• Nothing in the core lessons costs money. Optional and free at the time of writing, but check current terms: a live-preview extension for your code editor (for example Live Server for Visual Studio Code) or Python, if you need to serve the folder because saving does not work when you open the file directly; and a free file host if you choose to publish your finished app

My Task List: an app that remembers. Assemble one folder that holds a complete, interactive web app. The app is a task list with a form, a list you can tick and delete from, filter buttons, a menu, saved data and a Load sample tasks button that fetches live data. Two check files prove it works every time the page opens. Everything is code you wrote and understand. As a stretch goal, build a small quiz from the same parts. The finished deliverables are:

• index.html and style.css with a form, a summary line, filter buttons, a task list, a More menu and a status line
• check.js exactly as given, and tasks.js holding the rules of the app with no page code
• tests.js with at least twenty checks for the rules, all printing PASS
• app.js that connects the rules to the page using one state object, one render function, one listener on the list and a single function for the menu
• Saving and loading with localStorage that survives a reload and does not break on missing or corrupt saved data
• A Load sample tasks button that uses fetch, checks response.ok, shows a loading message and shows a clear message on failure
• app-tests.js, an end-to-end test that puts your real data back when it finishes and prints all PASS lines
• A short README.txt that says what the app does, how to open it and how to run the checks, plus your notes from the keyboard pass and the bad input pass

JavaScript From Zero: Make Web Pages Come Alive has 24 lessons in 6 modules, a workbook of 10 items and a capstone project. It is planned at about 7 hours in total. The lesson text runs to roughly 15,600 words.

JavaScript From Zero: Make Web Pages Come Alive has 6 modules:

• Module 1: Your First Working JavaScript. Set up a project folder, run code in the browser, store values in variables, work with numbers and text, and write your first functions. You finish with the first pieces of your task list app.
• Module 2: Decisions, Lists and Records. Make code choose between paths, keep collections of values in arrays, repeat work with loops, and describe a task as an object. You finish with a text version of the task list that runs in the console.
• Module 3: The Brain of Your App. Use filter and map to work with lists of tasks, update data by making new copies instead of editing, and write checks before code. You finish with the complete, tested logic file for the task list.
• Module 4: Connect Your Code to the Page. Learn what the DOM is, find and change elements, build list items from data, and react to clicks. You finish with a page that draws your tasks and adds a new one when you press a button.
• Module 5: Forms, Buttons and Menus. Handle a form safely, use one listener for many buttons, build a menu that opens and closes, and keep the whole page in step with one state object. You finish with a task list you can add to, tick off, delete, filter and clear.
• Module 6: Save It, Load It, Ship It. Save tasks so they survive a reload, load live data from the internet, find and fix bugs like a professional, and finish your capstone app with a full test run.

All 24 lesson titles, module by module:

• Module 1: Your First Working JavaScript. 1.1 Run your first JavaScript; 1.2 Store values in variables; 1.3 Work with numbers and text; 1.4 Write your own functions.
• Module 2: Decisions, Lists and Records. 2.1 Make decisions with if and else; 2.2 Keep lists in arrays; 2.3 Repeat work with loops; 2.4 Describe things with objects.
• Module 3: The Brain of Your App. 3.1 Pick items with filter; 3.2 Transform lists with map; 3.3 Update data without editing it; 3.4 Write the check before the code.
• Module 4: Connect Your Code to the Page. 4.1 Find elements on the page; 4.2 Change what the page shows; 4.3 Build list items from data; 4.4 React to clicks.
• Module 5: Forms, Buttons and Menus. 5.1 Handle a form; 5.2 Use one listener for many buttons; 5.3 Build a menu that opens and closes; 5.4 Keep the page in step with one state object.
• Module 6: Save It, Load It, Ship It. 6.1 Save tasks with localStorage; 6.2 Load live data with fetch; 6.3 Find and fix bugs; 6.4 Finish, test and share your app.

The course is listed at beginner level and planned at about 7 hours in total. It has 24 lessons, each with objectives you can check yourself against.

Lesson 1 is "Run your first JavaScript" (Module 1, Your First Working JavaScript). By the end of it the course says you will be able to:

• Open the browser console and read what it prints
• Load your own script file from an HTML page
• Run a check and tell a PASS line from a FAIL line

How Apex Flow Academy checks its courses

Yes for the core lessons, according to the course's own requirements list: "Nothing in the core lessons costs money." The list also names optional extras or costs outside the core lessons, so read it in full. Tool plans and prices change, so check each tool's current terms before you sign up.

Yes. The course lists this prerequisite: "No prior programming and no CSS knowledge are needed; the style sheet you need is given to you." It is listed at beginner level. It also asks for:

• Basic HTML: you can make an .html file with headings, paragraphs, lists, buttons and a form with a text box, and open it in a browser
• You can create folders and save plain text files on your computer

No. JavaScript From Zero: Make Web Pages Come Alive teaches and checks a skill, but it cannot promise an outcome. The course's own disclosure reads: "Created by Apex Flow Academy with AI assistance. For education only; not legal, tax, financial or medical advice. Results depend on your effort and circumstances."

Yes. JavaScript From Zero: Make Web Pages Come Alive includes a verifiable Certificate of Completion, issued by Apex Flow Academy when you finish every lesson, resolve every quiz question with at least 50% right on the first try, and tick the capstone checklist. It has a unique ID and a public verification page. It is a completion certificate, not a degree, licence, accreditation or exam result. The Full Operator path, with a final exam and capstone review, opens later with its own separate, stronger credential.
