These crawls are part of an effort to archive pages as they are created and archive the pages that they refer to. That way, as the pages that are referenced are changed or taken from the web, a link to the version that was live when the page was written will be preserved.
Then the Internet Archive hopes that references to these archived pages will be put in place of a link that would be otherwise be broken, or a companion link to allow people to see what was originally intended by a page's authors.
This is a collection of web page captures from links added to, or changed on, Wikipedia pages. The idea is to bring a reliability to Wikipedia outlinks so that if the pages referenced by Wikipedia articles are changed, or go away, a reader can permanently find what was originally referred to.
On December 5th 2015, Microsoft announced plans to open source the Chakra engine as ChakraCore, which will include all the key components of the JavaScript engine powering Microsoft Edge on their Github page under the MIT license in January 2016.[3] ChakraCore is essentially the same as the Chakra engine that powers the Microsoft Edge browser, but with platform-agnostic bindings, i.e. without the specific interfaces utilised within the Windows Universal App platform. On January 13, 2016 Microsoft released as promised ChakraCore under the MIT license on GitHub.[4][5]
