# == When to use components
#
# Components should be used with care. They're significantly slower than simply splitting reusable parts into partials and
# conceptually more complicated. Don't use components as a way of separating concerns inside a single application. Instead,
# reserve components to those rare cases where you truly have reusable view and controller elements that can be employed
# reserve components to those rare cases where you truly have reusable view and controller elements that can be employed
# across many applications at once.
#
# So to repeat: Components are a special-purpose approach that can often be replaced with better use of partials and filters.
