  • Requirements / Prerequisites
    • A foundational understanding of HTML and CSS is essential, as these are the bedrock upon which all web applications are built.
    • Basic familiarity with JavaScript, including concepts like variables, data types, functions, and control flow, will be highly beneficial.
    • While prior experience with any JavaScript framework is not mandatory, a willingness to learn and a curious mindset are crucial.
    • Access to a modern web browser (e.g., Chrome, Firefox, Safari) is required for viewing and testing your applications.
    • A code editor (e.g., VS Code, Sublime Text, Atom) will be needed to write and manage your project files.
    • A stable internet connection is necessary for accessing course materials and any required downloads.
    • No prior experience with Node.js or npm/yarn is strictly required, as the course will introduce the necessary concepts through ViteJS.
    • A desire to build and experiment is the most important prerequisite.
