  • On blockchain, no matter what buildings were lost, every record would be absolutely secure.The next step, according to Mari Khardziani, head of the international relations unit at Georgia’s National Agency of Public Registry, is to add the ability to incorporate “smart contracts” onto the blockchain itself, so that a Georgian…

  • Many React developers rely on Jest for a zero-configuration test runner and to produce code coverage reports.
  • And don’t discount the “rewrite factor” and time spent fixing comments from code reviews.
  • The advantage of letting React set your prop defaults, however, is that it produces more efficient code, defaults props in a based lifecycle component, as well as allows your default values to be checked against .
