Block Hooks

Briefly referred to as auto-inserting blocks.

Allows developers to attach blocks and insert them in specified locations:

before – inject before the target block.
after – inject after the target block.
firstChild – inject before the first inner block of the target container block.
lastChild – inject after the last inner block of the target container block.

See: Developer Resources > Block API Reference > Registration > Block Hooks
