In the Frontend Developer (Enhanced) course, students will learn advanced HTML and CSS skills. These skills are crucial for creating visually appealing and responsive websites. HTML is the foundation of web development, used to structure content on a webpage. CSS, on the other hand, is used to style and format HTML elements, making websites visually appealing to users. Understanding these languages is essential for frontend developers to ensure that websites are user-friendly, accessible, and aesthetically pleasing. By mastering these skills, developers can create websites that are both functional and visually engaging.

In the Frontend Developer (Enhanced) program, students will gain advanced proficiency in JavaScript. This includes a deep understanding of concepts such as closures, prototypes, asynchronous programming, and ES6 features. These skills are crucial for frontend developers as JavaScript is the backbone of modern web development. By mastering these concepts, developers can create dynamic and interactive user interfaces, handle data manipulation efficiently, and build scalable applications. Understanding JavaScript thoroughly allows developers to write cleaner, more maintainable code and solve complex problems effectively.

CSS (Cascading Style Sheets) is responsible for the layout and visual appearance of web pages. It allows developers to style HTML elements, control layouts, and adapt designs to different screen sizes through responsive design techniques. Including CSS in the assessment helps gauge a candidate's ability to create visually appealing and user-friendly interfaces. Proficiency in CSS is indicative of a developer's eye for design and detail, as well as their ability to translate design mockups into fully functional web pages.

jQuery is a fast, small, and feature-rich JavaScript library. It simplifies things like HTML document traversal and manipulation, event handling, and animation, making it much easier to use JavaScript on your website. Including jQuery in the assessment assesses a candidate's ability to leverage this library to streamline JavaScript coding. This sub-skill is important for evaluating whether candidates can efficiently use jQuery to enhance web applications' interactivity, performance, and user experience with less code and complexity.

Understanding web technologies encompasses knowledge of protocols, standards, and APIs associated with web development, including but not limited to HTTP, HTTPS, WebSockets, and RESTful services. This sub-skill is crucial for assessing a candidate's proficiency in using various web technologies to develop secure, scalable, and interactive web applications. It indicates a developer's ability to integrate different technologies and services into a cohesive web experience and troubleshoot issues related to web application performance and security.
