Node.js – EJS Function in Module

Node. js is really a JavaScript runtime that utilizes the V8 engine produced by Google for use within Chrome. V… compiles and completes JavaScript at super speeds largely because of the fact that V8 compiles JavaScript in to native computer code.

Along with super fast JavaScript delivery, the real miracle at the rear of Node. js is the big event loop. The event loop is really a single thread that works all I/O operations asynchronously. Typically, I/O operations either operate synchronously (blocking) or asynchronously through spawning off parallel threads to do the work. This old approach consumes lots of memory and is infamously difficult to program. In comparison, when a Node application must perform an I/O procedure, it directs an asynchronous process towards the event loop, along having a callback function, and then is constantly on the execute the rest associated with its program. When the actual async operation completes, the big event loop returns to the duty to execute its callback.

Quite simply, reading and writing in order to network connections, reading/writing towards the filesystem, and reading/writing towards the database–all very common duties in web apps–execute really, very fast in Node. Node enables you to build fast, scalable network applications able to handle a huge number associated with simultaneous connections with higher throughput.
