You can only use an effect if somewhere up the call stack there is a place where that effect will be handled. In Java you need a catch around every throw, even if for runtime exceptions you can skirt around this slightly. In languages with async/await you must decorate a call to an async function with await, and the function you’re calling from must be async. Eventually up the call stack you’ll get to a call that adds the async work to a task queue, executor, or blocks waiting for it to complete. These are all examples of effect handlers for async programming. They provide the scheduling effects that the async code needs in order to run.
Robot vacuum prices often trend in the high hundreds of dollars, so for under $300 this model from Shark is a real steal. It maps your home using 360° LiDAR technology, allowing it to clean methodically while detecting and avoiding obstacles like shoes or furniture. It also has a bagless design and a self-emptying base. Here it can hold up to 60 days of dirt, while HEPA filtration captures 99.97% of dust and allergens. If you have pets at home, the self-cleaning brush roll will become your new best friend — say goodbye to vacuum hair tangles.
