In simpler terms, hooks work as the entry points that enable you to latch onto or ‘hook into’ strategically specified key areas of the WordPress code.

Breaking them down further, there are two main types of hooks employed in WordPress — actions and filters. Both have their part to play, but the one hook that serves our exploration today falls in the filter category, which is used to modify various aspects of the platform. Our subject of interest, query_loop_block_query_vars, is one such hook.
