  6. APIs and Data Manipulation: Experience in working with RESTful APIs, JSON manipulation, data fetching, and data manipulation using JavaScript.

  7. Browser APIs: Knowledge of various browser APIs (e.g., Fetch API, Web Storage API, Geolocation API) and their usage in web applications.

  8. Debugging and Testing: Proficiency in debugging JavaScript code using browser developer tools and knowledge of testing frameworks (e.g., Jest, Mocha) and techniques for unit testing JavaScript applications.

  9. Performance Optimization: Understanding of techniques to optimize JavaScript code and improve application performance, including minification, code splitting, lazy loading, and caching strategies.

  10. Collaboration and Communication: Effective communication skills to collaborate with designers, other developers, and stakeholders in a development project, understanding requirements, and translating them into JavaScript solutions.
