Terminology: What is a “glitch” in Functional Reactive Programming / RX?

Question

What is the definition of a \"glitch\" in the context of Functional Reactive Programming?

I know that in some FRP frameworks \"glitches\" can occur while in others n

Short answer : glitch = inonconsistent/illegal/meaningless state.

And a relevant SOF answer : how to avoid glitches in Rx

So here is my understanding of what a glitch is based on Tomas' answer.

There is a dataflow graph, with 3 nodes : A, B, C

A->B

A->C

In this simple example, a glitch happens if I change A and that causes to change B but C has not been updated yet. This is a glitch.

C is not consistent with B.

Say B=2*A, C=2*A.

Then if B is not equal C then that is a glitch.
