Job Responsibilities:
  • Development of core Javascript libraries.
  • Writing reusable code or modules that can be used across all the Javascript libraries.

  • Good Javascript Debugging Skills. You will have to debug almost all the websites out there day in day out.
  • Passion to write automated tests to verify the working of libraries (You canā??t possibly verify things on all devices and on all browsers manually).
