![]() myMethod, 2000 ) // error: "NS_ERROR_XPC_BAD_OP_ON_WN_PROTO: Illegal operation on WrappedNative prototype object" setTimeout. Each of the Timeout objects returned by these functions export both timeout.ref() and timeout.unref() functions that can be used to control this default behavior. In fact, it will be an error because setTimeout code expects this to be the window object: setTimeout. By default, when a timer is scheduled using either setTimeout() or setInterval(), the Node.js event loop will continue running as long as the timer is active. call won't work // because this will change the value of this inside setTimeout itself // while we want to change the value of this inside myArray.myMethod. myMethod, 1500, "1" ) // prints "undefined" after 1,5 seconds // Passing the 'this' object with. myMethod, 1000 ) // prints "" after 1 second setTimeout (myArray. setInterval() takes a function argument that will run an infinite number of times with a given millisecond delay as the second argument. myMethod ( 1 ) // prints "one" setTimeout (myArray. Node.js provides clear functions for stopping or canceling the execution of the Timeout or Immediate objects. It supports the expected setInterval parameters with an extra optional one for specifying the number of repetitions to be done.MyArray. Clearing Node.js timer functions setTimeout(), setInterval(), and setImmediate() all return an object that may be used to refer to the Timeout or Immediate objects, respectively. ![]() So I implemented my own setInterval function which tackles the above mentioned shortcomings. On top of the previously mentioned shortcomings, I'd really appreciate if setInterval had an optional parameter for setting the number of repetitions instead of repeating infinitely. If for some reason, an error occurs in part of the code that is called by setInterval, it wouldn't break and keeps executing the faulty code. setInterval starts a function every n milliseconds, without any consideration about when a function finished its execution. Despite being useful in many applications, setInterval's shortcomings could blow up your. This is were the native setInterval function comes to use. If you use Javascript often you might have come across the need for delaying the execution of code within intervals of time with repetition. What would happen is that you'll end up with a bunch of queued requests that may not necessarily return in order. An alternative to Javascript's evil setInterval. Node.js node.js sockets http Node.js req node.js session express sails.js Node.js ''index.jsmailchimp node.js module Node.js Google node.js reactjs Node.js JSON0. Consider using setInterval to poll a remote server every 5 seconds, network latency, unresponsive server and other variables might prevent the request from completing on time. In some cases, the function might need longer than the interval time to finish execution. Why is setInterval evil? Doesn't care whether the callback is still running or not Despite being useful in many applications, setInterval's shortcomings could blow up your application in some circumstances. In particular, they are supported in all browsers and Node.js. But most environments have the internal scheduler and provide these methods. These methods are not a part of JavaScript specification. ![]() If you use Javascript often you might have come across the need for delaying the execution of code within intervals of time with repetition. setInterval allows us to run a function repeatedly, starting after the interval of time, then repeating continuously at that interval. ![]()
