I am inclined to disagree.
Displacement is a vector with magnitude and direction. DISTANCE is the scalar magnitude of displacement.
However Work, for example in Joules, is clearly scalar and has no direction. It is a dot product of force and displacement vectors and has no direction.

Components of vectors such as components of a force vector are also scalars. They are the dot product of the vector with the unit vector in the component direction.

For example Fx = F dot i = |F|cos of angle to x axis
