- JavaScript (Interactive and Maintainable Code): Proficiency in modern JavaScript (ES6+) including promises, async/await, and modular code is essential for dynamic features like form validation, animations, and real-time interactivity, all enhancing user engagement.
Why it matters: Solid command of these core web technologies is non-negotiable for building performant, accessible, and SEO-friendly marketing websites.
