-
Requirements / Prerequisites
- Solid grasp of core JavaScript fundamentals: Proficiency with ES6+ syntax, asynchronous JavaScript, modules, classes, and fundamental data structures is essential.
- Familiarity with the Node.js ecosystem: Basic understanding of npm or yarn, package management, and executing JavaScript outside the browser.
- Working knowledge of the command line interface (CLI): Comfort with navigating directories, executing commands, and interacting with developer tools via the terminal.
- Basic understanding of web development concepts: Awareness of how JavaScript interacts with HTML and CSS, and the build process in general.
- Prior exposure to a modern JavaScript framework (e.g., React, Angular, Vue) is beneficial but not strictly required.
- Conceptual understanding of software development principles: Including version control (Git), testing methodologies, and deployment basics.
- Strong desire to master JavaScript build processes and complex configurations.
-
Skills Covered / Tools Used
