Note: This feature is available in Web Workers, except for Service Workers. The Worker interface of the Web Workers API represents a background task that can be created via script, which can send messages back to its creator. Creating a worker is done by calling the Worker("path/to/worker/script") constructor. Workers may themselves spawn new workers, as long as those workers are hosted at the same origin as the parent page. Note that not all interfaces and functions are available to web workers. See Functions and classes available to Web Workers for details. Creates a dedicated web worker that executes the script at the specified URL. This also works for Blob URLs. Inherits properties from its parent, EventTarget. Inherits methods from its parent, EventTarget. Sends a message - consisting of any JavaScript object - to the worker's inner scope. Immediately terminates the worker. This does not let worker finish its operations; it is halted at once. ServiceWorker instances do not support this method. Fires when an error occurs in the worker. Fires when the worker's parent receives a message from that worker. Fires when a Worker object receives a message that can't be deserialized. For a full example, see our Basic dedicated worker example (run dedicated worker). BCD tables only load in the browser with JavaScript enabled. Enable JavaScript to view data. Support varies for different types of workers. See each worker type's page for specifics. In early versions of the spec, loading a cross-origin worker script threw a SecurityError. Nowadays, an error event is thrown instead.
With no warning, your washing machine has become violently mutinous. As you watch in horror, its typical spin cycle goes psycho. The entire possessed unit vibrates across the floor toward you, with the lid flung open and untold gallons of water spewing, soaking your basement and sinking your savings account. It's probably time to buy another one. Whether your older appliances have gone berserk or just really need updating, the used-appliance market is always an option. But it's best to understand the pros and cons of used equipment before you spring for the first refrigerator you find on a classified ad Web site. What's more, there's a certain element of risk that comes into play every time you buy a used product, whether it's a car, camera or dryer. We'd love to vouch for specific product categories and their general reliability on the used market. However, product quality varies so much from manufacturer to manufacturer (and even within products made by one company), that it's difficult, if not impossible, to say that ovens, for example, are always a great deal when you find them used.
That's why you have to shop smart, be observant and always, always do your homework before you buy. We have vital pointers to share for when you go shopping for these necessary appliances. Keep reading, and you'll see how to replace your demonic washer with one that doesn't leave you all wet. Major appliances such as refrigerators, gas ranges and freezers generally need little in the way of maintenance and repairs. Another key point: They are often the most expensive to purchase in squeaky-clean, brand-new condition. Those large appliances are the most costly, but they also have the longest lives. A full-size refrigerator can last around two decades with almost no maintenance. Perhaps they remodeled their kitchen and the old fridge looks horribly out of place. Or maybe an elderly gentleman with a bad back just can't stoop to use a side-loading washing machine anymore. These cast-off products are in great working condition, and you can nab them for a fraction of the new purchase price.
Even if your bargain buy conks out after just a few years of use, there's a very good chance you'll still have saved money in the long run. A couple of exceptions might be built-in refrigerators and gas cooktops. Similarly, if you're trying to decide between repairing a broken appliance or buying another one, the Consumer Reports advice is simple -- if the cost of the repair is more than half of the price of a new (or great, used) product, don't even consider the repair. Your local appliance store can be a bonanza for bargain shopping if you know where to look and which questions to ask. You just have to do a bit of investigating. Although they don't technically count as used, the scratch-and-dent sections of appliance, hardware and home furnishing stores often have unbelievable deals. You might find a top-end refrigerator with an unfortunate but superficial dent on the side, and at a price hundreds of dollars lower than models in mint condition.
For those kinds of savings, you can find plenty of ways to disguise that flaw. And if your store doesn't seem to have any, you can always inquire about floor models. Many outlets will part with these demonstration models (which have been pawed at and caressed by hundreds of potential buyers) at a steeply discounted price. With floor and scratch-and-dent deals, you may not get a full warranty, but you might well receive what's left of the active warranty, which you probably won't find from a private seller. A warranty (albeit a shorter and more limited one) is even more likely if you choose a refurbished or remanufactured model sold at a retail outlet. You'll save a lot of money and have the added benefit of peace of mind. And here's another pointer: When it comes to damaged or discolored appliances, there are two miraculous words that can change everything: spray paint.
