initializer_list advantages c++11

Question

Hi All
I am pretty much aware about class constructor using member initialisation... This is available before c++11 I guess...
However, consider below example :
https://code.sololearn.com/cosnYLm273jK/?ref=app
Is this initializer_list new in c++11 ? Why would anyone need this ? Any specific reason to introduce this?
I tried to search for some article , but it talks about only class member initialisation...
Any thoughts / pointer would be helpful. Thanks a lot
