Introduction to Frontend Development

Frontend development focuses on the visual and interactive parts of a website. It involves technologies like HTML, CSS, and JavaScript. Surprisingly, 50% of a website’s performance depends on frontend optimization.

HTML stands for HyperText Markup Language. Semantic tags like <article>, <section>, and <nav> improve accessibility and SEO. Interestingly, semantic tags can boost page load speed by 30% when used correctly.

CSS makes websites visually appealing. Media queries enable responsive design, ensuring websites look good on all devices. Did you know that a well-optimized CSS can reduce website bounce rates by up to 40%?

JavaScript adds interactivity to web pages. Libraries like React and Vue.js streamline development. Shockingly, JavaScript code can be 10x faster when utilizing WebAssembly for performance-critical functions.

Tools like Webpack and Babel optimize frontend workflows. Adopting best practices such as code splitting can improve load times. Fun fact: Progressive Web Apps (PWAs) can make websites perform similarly to native apps, enhancing user experience.

Incredibly, 75% of users judge a website's credibility based solely on its design within the first 10 seconds of their visit.
