- Enhance page load performance using defer and async attributes for loading JavaScript files.
- Work with Figma or similar tools to convert modern UI/UX designs into clean, reusable, and modular components.
- Apply best practices in CSS, including layout techniques (Flexbox, Grid), specificity management, and cross-browser compatibility.
- Optimize applications for first contentful paint (FCP) and time to interactive (TTI) by understanding DNS resolution, TLS handshakes, and script execution timing.
- Write and differentiate between arrow functions and regular functions in JavaScript for effective memory usage and context management.
