 - **Role**: JavaScript adds interactivity and dynamic behavior to web pages. It enables features like form validation, content updates without page reloads, and interactive elements like sliders and carousels. In other words, while CSS makes it look “good”, JavaScript makes it interactive and reactive to the user’s actions.
 - **Key Features**: Modern JavaScript (ES6+) introduces features like arrow functions, template literals, destructuring, modules, and promises. These features make the code more concise and readable. Whether you’re an old developer looking to become a front end developer, or a new one just getting started, adopting these features is key to your success as a JavaScript developer.

As a front end developer you have control over how the page is rendered, including how fast it does it and the information that is provided to search engines In other words, you have full control over the traffic and visibility of the project you’re working on.
 - **Career advancement**: As businesses increasingly recognize the importance of online presence, the demand for developers with SEO expertise is growing. Front End developers who can implement SEO best practices are more valuable to employers and clients, leading to better - job opportunities and career growth.
 - **Improved code quality**: SEO-friendly code is usually cleaner, more organized, and easier to maintain (there are no guarantees though). By adhering to SEO best practices, front end developers tend to produce code that is well-structured and follows industry standards, leading to fewer bugs and more scalable projects.
