getrefrecord still a valid feature to be used

[Anubhav24]

Hi All,

I am wondering if getreference with a callback function is still  a relevant feature which we can use or do we have something else or do we always need to use GlideAjax if we need some values from backend to frontend.

Also does it hampers the performance even if it is used in a callback function.

Thanks in advance.
