Explain the mechanics and objectives of "speedrunning" in Minecraft and the strategies employed by speedrunners to complete the game as quickly as possible.

Speedrunning in Minecraft involves completing specific objectives or defeating the Ender Dragon (or other bosses) in the shortest amount of time possible. Speedrunners utilize various strategies such as optimized route planning, resource management, glitch exploitation, and precise execution of game mechanics to achieve record times. Techniques like block clipping, nether portal travel, and coordinated trades with villagers are commonly used to skip or streamline progression and overcome obstacles more efficiently.
