This is a basic course to strengthen the students ability to understand the basics of programming and Web Development. At the end of the course, the students will develop an interest in programming with a good theoretical and practical knowledge of how things work.

This course aims to be an introduction to the basic principles of web development, starting with the basic structure of any website: HTML (HyperText Markup Language).

This is a course for those who want to get started in the world of web development.

Please note that no prior knowledge is required to begin this course.

I offer personalized academic support for primary and secondary school students to help them improve their understanding, confidence, and performance in school. My lessons focus on explaining concepts in a simple and clear way, assisting with homework, test preparation, and strengthening weak areas.
I adapt my teaching style according to each student’s learning needs and pace. Whether your child needs regular academic support, exam preparation, or help with specific subjects, I provide structured and supportive lessons in a friendly learning environment.
My goal is to help students build strong foundations, develop good study habits, and achieve better academic results with confidence.

This module is a crucial step for any web developer wishing to move from simple DOM manipulation to mastering modern frameworks. The objective is clear: to understand the "invisible foundations" of the language in order to write shorter, more readable code and, above all, be ready to code professionally in React.

🎯 Training Objectives

1- Demystify the modern syntax (ES6+) often used in React.
2- Increase efficiency by using the most powerful syntactic shortcuts.
3- Secure your code to avoid frequent bugs related to missing data.
4- Mastering asynchronicity to manage data calls (API).

📖 Detailed program content

The course is divided into 13 key concepts, illustrated by comparative examples (classic syntax vs. modern syntax) and concrete use cases in React:

1- Ease of writing: Use of Template Literals (`backticks`) for dynamic character strings and Shorthand property names to simplify the creation of objects.

2- Logic and Functions: Mastery of Arrow => Functions (arrow functions) and their implicit return, essential for React components and hooks.

Data manipulation:

1- Destructuring (decomposition) to properly extract data from objects and arrays (e.g., Props and States).

2- Rest & Spread Operators (...) to copy arrays or merge objects without modifying the original (concept of immutability).

Code robustness:

1- Managing default parameter values.

2- Advanced security with Optional Chaining (?.) and Nullish Coalescing (??) to prevent application crashes.

3- Functional Programming: Intensive use of array methods (.map(), .filter(), .reduce(), .find()) to transform data into user interfaces.

4- Architecture and Asynchronism: Code organization via modules (Import/Export) and API request management with Promises and Async/Await.

🛠️ Teaching method: "Learning by doing"

This course is not just about theory. It includes:

The "Interstellar Dashboard" Exercise: A 15-minute thematic case study where students manipulate data from space missions. This allows them to immediately apply destructuring, filtering, and asynchronicity to a real-world project.

The Interactive Quiz: A series of 10 questions designed to validate understanding of each concept before moving on. Each question presents real-world scenarios that developers will encounter in React.

🚀 Learner's result

By the end of this course, students will not only "know" JavaScript; they will understand why and how each syntax is used to build efficient React components. They will leave with a solid foundation to confidently tackle Hooks (useState, useEffect) and complex state management.

Format: Clean visual presentation, coloured syntax for code, and focus on readability.

Want to learn how to build real websites and web applications from scratch, even if you have no prior experience? 💻✨
You can choose from classes on specific topics or the complete Web Development Course. You'll learn, in a practical and progressive way, the skills needed to create responsive web pages and websites (for viewing on mobile devices or all types of screens), regardless of your academic level or age. Teenagers, young adults, adults; anyone can learn, all you need is the desire! I am a frontend developer and psychomotor therapist with over 20 years of experience in teaching and learning processes, focusing on the individual needs of each learner.

This class is designed for students, young adults, or professionals who want to better understand computer science and programming, whether they are beginners or already have some experience.

I focus on helping students understand concepts deeply, not just memorize syntax. Topics can include programming fundamentals, algorithms, problem-solving, debugging, and practical projects using languages such as Python, JavaScript, HTML/CSS or SQL, depending on your goals.

My teaching approach is structured, progressive and adapted to each student’s level. I take the time to explain complex ideas in a clear and concrete way, using real-life examples and hands-on exercises.

Lessons can be oriented toward:
- discovering programming from scratch
- strengthening academic knowledge
- preparing exams or technical interviews
- supporting career change or personal projects

Between sessions, I may suggest small exercises or mini-projects to help consolidate what we’ve learned, always at a pace that keeps students motivated, not overwhelmed.

This online programming class is designed for students who want to build real technical skills in computer science and web development — not just learn theory, but actually create and understand how systems work.

I teach:

• Python programming (fundamentals, logic building, problem-solving, data handling)
• JavaScript (core concepts, DOM manipulation, interactivity)
• CSS (styling, layout systems, responsive design)
• Website Development (front-end foundations and structure)
• WordPress Development (customization, site building, content management)
• UI/UX Fundamentals (design thinking, layout clarity, user experience principles)

Students learn how to think computationally, break down problems logically, and build structured solutions. Lessons are practical and project-based, meaning students don’t just watch — they build.

For beginners, we focus on strong foundations: understanding how code works, writing clean syntax, and developing confidence in debugging.
For intermediate learners, we move into structured projects such as creating simple websites, improving layout design, adding interactivity, and understanding how front-end components connect.

My approach emphasizes clarity, structure, and application. I help students understand not only what to type, but why it works — which is the difference between copying code and truly understanding it.

This class is suitable for:
• School students exploring computer science
• Beginners transitioning into tech
• Learners preparing for academic computer science courses
• Individuals interested in web development skills

All sessions are fully online, interactive, and tailored to the student’s pace and goals.
