I have this GN setup:
I expected that if i unmute the mesh to curve node, that i got a curve...but i got...nothing.
Why don't i get a curve with half of the number of my resolution?
even the spreadsheet looks ok:

1$\begingroup$ Is there a reason why you're not using the Resample Curve node to do that ? $\endgroup$– GorgiousCommented Nov 24, 2021 at 12:20

$\begingroup$ It’s just an example, It would like to know how I can delete vertices in a curve 😉 $\endgroup$– ChrisCommented Nov 24, 2021 at 12:26

$\begingroup$ Alright I figured so. :) What about the Delete Geometry node then ? $\endgroup$– GorgiousCommented Nov 24, 2021 at 12:39

1$\begingroup$ Btw to add my point of view to your question I think it's because a mesh's vertices are not spatially ordered (if a mesh contains only vertices, you can swap vertex indices without the mesh changing) whereas the order in which control points are defined in a spline define the shape of the spline. $\endgroup$– GorgiousCommented Nov 24, 2021 at 12:41

You can use a Delete Geometry node to selectively remove control points from a curve geometry without having to convert it to and from mesh geometry.
You can add any field output in the Selection input of the Delete Geometry node, so long at it can be evaluated as a boolean (True, False) for each control point of the curve geometry.
A Value of True (or number > 0) will delete the control point, when a value of False (number <= 0) will keep it.
