-    component_type(g)

+The type of the components of the elements of `gf`. I.e if `gf` is a vector
+valued grid function, `component_view(gf)` is the element type of the vectors
+at each grid point.
 
-The type of the components of the coordinate vector of `Grid` `g`.
+# Examples
+```julia-repl
+julia> component_type([[1,2], [2,3], [3,4]])
