node js break for loop

building high-performance, highly scalable Internet applications-because it handles massive and high-throughput concurrent connections.How it works is quite interesting. The traditional Network Service technology, is each new connection (request) will generate a new thread, this new thread will occupy the system memory, will eventually take up all the available memory. While node. JS is only running in one

. Lazy assignment Although lazy assignment can be implemented using the closure of JS, yield can be greatly simplified. by pausing and restoring it, we can obtain the value when we need it, for example, the above Figen function can pull a new value as needed: Var fibIter = fig (20) var next = fig. next () console. log (next. value) setTimeout (function () {var next = fibIter. next () console. log (next. value)}, 2000) of course, The for

inability to play a performance advantage. Despite the failure, Ryan Dahl generally felt that the key to solving the problem was to achieve the goal through event-driven and asynchronous I/O.As soon as he was desperate, the V8 engine came. V8 meets his imagination about high-performance Web servers: No historical baggage, no synchronous I/O. There is no situation where a synchronous I/O causes a dramatic decrease in event loop performance.

Detailed description of Node. js Streams file read and write operations, node. jsstreams Node. js is inherently asynchronous and event-driven, and is very suitable for processing I/O-related tasks. If you are dealing with I/O-related operations in the application, you can us

* * logic Control as the core of JS programming, in the coding is most commonly used, then in the process of using some common problems need to use a specific statement to achieve. We use more is the circular statement, in the circular statement, there must be meet the conditions or do not meet the conditions to jump out of the cycle of the moment, this time to use the circular concluding sentence, is usually used to

#events (take a closer look at events, there may be other parts you want to use)But just in the console output, want to display the progress bar at the front end is not possible (not to study, think of other ways should also be able)　　4.

of Node is the construction of high-performance, highly scalable Internet applications-because it can handle massive and high-throughput concurrent connections. Its working principle is quite interesting. The traditional network service technology generates a new thread for each new connection request. This new thread will occupy the system memory and eventually occupy all available memory. Node.

Another Let's look at the code first. snandy: The Code is as follows: Var ary = ["jack", "tom", "lily", "andy"];For (var I = 0, a; a = ary [I ++];) {Console. log ();} Still pay attention to the conditions for running the for Loop: a = ary [I ++]. Note that here is = rather than =. If it is =, the loop

event queue during execution, the program enters the event loop at execution time, waits for the next event to arrive, and each asynchronous I/O request is pushed to the event queue for processing by the program process."Figure" node. JS Schema2nd. Installing and configuring node. jsnode.
