1. AI Assisted Development

The introduction of GitHub Copilot in 2022 marked a significant milestone in web development, showcasing the potential of AI integration within Integrated Development Environments (IDEs). GitHub Copilot has been a valuable tool for developers, enhancing code efficiency and quality.

Looking ahead to 2023, we anticipate further advancements in AI assistants, leading to significant impacts on development practices. It is likely that developer reliance on traditional resources like MDN may diminish as AI tools provide more immediate and contextual support. Furthermore, the emergence of new platforms, such as Prompt Overflow, could reshape how developers seek and share knowledge.

2. Rendering Patterns

In 2022, Vercel introduced a shift in rendering decisions, moving from a one-time application-wide choice to a component-specific determination. This change reflects the increasing complexity and sophistication required in front-end development, particularly with technologies like Streaming SSR and Progressive Hydration.

The year 2023 is expected to witness the adoption of more nuanced rendering patterns by frameworks, potentially leading to innovations such as per-line rendering (PLR). This evolution may also drive demand for specialized roles, such as Rendering Reliability Engineers, in the industry.

3. JS Runtimes

The introduction of Deno and Bun by the creator of Node.js has added to the diversity of JavaScript runtimes, expanding the language's capability to operate in various environments. These new runtimes have significantly optimized web performance metrics like Time to First Byte (TTFB).

In 2023, the trend towards faster and more specialized JavaScript runtimes is expected to continue. We may see the launch of new runtimes like Boil, aimed at specific applications, further enhancing the efficiency and scope of JavaScript-based applications. This progression signals a vibrant and innovative future for web technology.
