Transient props in Styled Components

StyledComponents

Today I learnt about transient props in Styled Components.

What issue it resolves?

When creating a styled component with a prop which is similar to an existing HTML attribute, that prop gets passed through to the underlying DOM element as a corresponding attribute. We could handle it by renaming that prop to not match any existing HTML attribute.

This new props now enables us to pass the same props with $ prefixed to them, and styled components will know not to pass these to the rendered DOM element nor pass it further down the component hierarchy.
