3.11 Use sustainable JavaScript and APIs

Web Development

Write efficient JavaScript and use APIs that minimize processing, data use, and energy consumption.

Success Criteria

  • Sustainable JavaScript:
    Write JavaScript that supports long-term application performance by reducing unnecessary calculations, limiting DOM updates, and minimizing network requests.
  • Energy-relevant APIs:
    Leverage JavaScript APIs, such as Compression Streams, Page Visibility, or Vibration, when they help reduce energy use or improve efficiency.
  • API requests:
    Only call client-side or server-side APIs when needed. Ensure only data required for the task is included in requests and responses.
