This is the main function to execute our code. `world.beforeEvents.playerPlaceBlock.subscribe()` will run before any block is placed.

- `const player = event.source;` defines the variable `player` as whatever the source of the event is (the one who is placing the block). `const` is used over `var` or `let` to say that the source _cannot_ be changed, and is constant.

- The `if()` statement requires the criteria to evaluate to true in order for the code within the brackets to run.
- `event.permutationBeingPlaced.type.id === 'minecraft:bedrock'` verifies that the block being placed is 'minecraft:bedrock'.
- `event.block.typeId != "minecraft:frame" && event.block.typeId != "minecraft:glow_frame"` checks that the block being targeted is not an item frame, so that the block whose placement is being canceled can still be placed in item frames.
