Could an Arcade function be added that would explode geometries into separate lines for each segment?

That would be helpful when doing complex analysis on polyline segments.

@JohannesLindner @Thanks, what I meant was: explode a given polyline part into multiple 2-vertex segments (split at each vertex).

I don't know... Seems like a quite narrow use case to make a function for. Plus, you can easily do it yourself:

function explode_polyline(geo) {
    var segments = []
    for(var p in geo.paths) {
        for(var q = 1; q < Count(geo.paths[p]); q++) {
            var point0 = paths[p][q-1]
            var point1 = paths[p][q]
            Push(segments, Polyline({"paths": [[point0, point1]], "spatialReference": geo.spatialReference}))
        }
    }
    return segments
}


Console(explode_polyline(Geometry($feature)))

@JohannesLindner Fair enough.

@KoryKramer, feel free to close. Cheers.

As noted, each segment can be obtained by looping through the vertices of the geometry.
