The verdict in three sentences
If you can already build a page in HTML and CSS in Thies, JavaScript is the skill that turns a static showcase into a tool an SME actually uses. A focused 16-hour course at 75,000 FCFA (115 EUR) is enough to lay solid foundations, while a bootcamp costs 500,000 to 1,500,000 FCFA. Interactive website jobs bill at roughly 150,000 to 500,000 FCFA in 2026, and your portfolio decides where you land in that range.
Why JavaScript after HTML and CSS
In Thies, between Iba Der Thiam University, the Polytechnic School and vocational training centers, there is no shortage of HTML and CSS integrators. What is missing are people who can make a site useful: a form that checks its fields, a price calculated live with 18% VAT, a cart that remembers items, an order sent over WhatsApp. Local shops, private schools and service providers working with Dakar ask for these features.
| What the client asks for | JavaScript skill | Indicative job price in 2026 |
|---|---|---|
| Price calculator in FCFA with VAT | Variables, functions, events | 50,000 to 150,000 FCFA (add-on module) |
| Validated registration form | DOM, validation, error messages | 50,000 to 100,000 FCFA |
| Catalogue with search and filters | Arrays, objects, filter and map methods | 150,000 to 300,000 FCFA |
| Persistent cart and WhatsApp order | localStorage, link generation | 200,000 to 500,000 FCFA |
| Page fed by an API | fetch, async and await | 100,000 to 250,000 FCFA |
| Complete interactive showcase site | All of the above | 150,000 to 500,000 FCFA |
These rates are 2026 orders of magnitude observed in Senegal. They do not guarantee any income.
Comparing ways to learn in Thies
| Option | 2026 price | Length | What you get |
|---|---|---|---|
| Free YouTube tutorials | 0 FCFA, data aside | Unlimited | Copied code snippets, rarely understood |
| International online certificate | 15,000 to 50,000 FCFA | 20 to 40 h | Theory in English, out-of-context examples |
| Bootcamp in Dakar | 500,000 to 1,500,000 FCFA, plus travel | 3 to 6 months | Intensive coaching, heavy schedule |
| Kolonell, JavaScript (level 3, Intermediate) | 75,000 FCFA (115 EUR, about 130 USD) | 16 h | 6 modules, 83 exercises, 2 graded projects, certificate |
| Full Web development track (5 levels) | 350,000 FCFA instead of 450,000 | 5 courses | From first code to full-stack |
The JavaScript: make a website come alive and interactive course is level 3, Intermediate, of the Web development track, and it is taught in French. It costs 75,000 FCFA for 16 hours, payable by Wave or Orange Money. You relearn the language from the start: variables, conditions, loops, functions, arrays and objects, then the DOM and events, form validation, localStorage, fetch and async/await over 3G, module organization, debugging and going live. It has 6 modules, 30 lessons, 83 graded exercises, more than half of them in code, and a verifiable certificate.
If you are starting from zero, the Web development track bundles all 5 levels for 350,000 FCFA (about 534 EUR) instead of 450,000, from discovering code to full-stack developer.
The 3 portfolio projects
- A price calculator for a Dakar service provider, with FCFA amounts and 18% VAT (graded project).
- A page fed by a public API, loaded with fetch and designed for a 3G connection.
- An interactive catalogue with search, filters, a persistent cart and WhatsApp ordering (graded project).
These three live projects carry more weight than a diploma with a Thies shopkeeper: he sees what you can do in two minutes on his phone.
Mini case study
Moussa, 21, a computer science undergraduate in Thies, already builds HTML and CSS pages for friends and family. He completes the 16-hour course over four weeks and pays 75,000 FCFA by Wave.
Learn this skill with Kolonell Academy
Short, practical online courses (taught in French), graded exercises, certificate. Pay with Wave or Orange Money.
Using his online catalogue as a demo, he offers a spare parts shop on the Dakar road a catalogue with cart and WhatsApp ordering, billed at 250,000 FCFA. He then adds a booking form for a driving school at 75,000 FCFA.
- Income from the first two jobs: 325,000 FCFA
- Course cost: 75,000 FCFA
- Net gain: 250,000 FCFA, course paid back by the first job
This case is an order-of-magnitude example. The outcome depends on portfolio quality and real outreach.
FAQ
Do I need HTML and CSS before starting?
Yes, the course targets people who can already build a page. If that is not you yet, level 2 HTML and CSS of the track comes first.
How long does it take to learn JavaScript?
The course lasts 16 hours. At 4 hours a week, plan on about 4 weeks, then 1 to 2 months of practice before delivering your first jobs.
Can I take the course on a 3G connection?
Yes, lessons are designed for mobile connections and the fetch module deals specifically with slow loading. A 5,000 to 10,000 FCFA monthly data plan is usually enough.
How much should I charge for an interactive site in Thies?
As a 2026 order of magnitude, 150,000 to 500,000 FCFA for a site with a calculator or catalogue, and 50,000 to 150,000 FCFA for an add-on module. No income is guaranteed.
What comes after JavaScript?
Level 4, React and Next.js, at 100,000 FCFA, opens up web applications. The full track comes to 350,000 FCFA instead of 450,000.
