I get the following error when executing the command "ng new projectname"

core-js@2.6.10: core-js@<3.0 is no longer maintained and not recommended for usage due to the number of issues. Please, upgrade your dependencies to the actual version of core-js@3.

Why is this happening, and how can I get rid of this error?

  • It's not necessarily an _error_, it's just a warning message that indicates that version 2 of the `core-js` dependency is no longer maintained. You can safely ignore it. – Edric Dec 03 '19 at 12:24
  • @Edric Thank you for your response. It seems like when I run the angular application, I get another template than normally, where did this change come from? Normally I would see a particular template after doing ng start --open, but now I see another template. Why is that? – M Yil Dec 03 '19 at 13:40
