An electrostatic field is an electric field that is produced from a non-changing charge distribution with no current (i.e. $\mathbf J=0$ at all points in space for all time). Essentially for electrostatics we just have stationary charges and constant electric fields.
If this is not the case, then resulting electric fields are not considered to be a part of electrostatics. i.e. moving charges, EM waves, etc.

$\begingroup$ Can you also add, how that difference can affects anything else? $\endgroup$– GouravMCommented Oct 25, 2019 at 22:02

$\begingroup$ @GouravM That's a pretty broad question. I don't think I can answer it unless you have a specific system in mind. And even then the comments are not a place to discuss it. If there is a system you want to learn more about, it might be good to ask a new question. $\endgroup$ Commented Oct 25, 2019 at 22:08
