2. Programming Language Support:
   • Cypress supports JavaScript exclusively, which can be limiting for teams using other languages.
   • Selenium supports multiple programming languages, including Java, C#, Python, and Ruby, offering more flexibility.
3. Testing Capabilities:
   • Cypress excels in end-to-end testing with its automatic waiting for commands and real-time reloading.
   • Selenium offers comprehensive cross-browser testing and integration with Selenium Grid for parallel test execution.
4. Ease of Use:
   • Cypress has a simple setup process and an intuitive API, making it easy to get started.
   • Selenium requires more configuration and setup, but it provides more customization options.
5. Performance:
   • Cypress runs tests faster due to its architecture and direct browser control.
   • Selenium may have slower test execution times, especially when running on remote servers.
