Learn callback functions and blocking functions with examples.Thats why a ton of the internal Node APIs accept callback functions as arguments rather than returning data you can assign to a variable. I need a guidance in reading node.js documentation. Many node functions has " callback" as their last argument. However, the documentation doesnt say what should be the arguments of these callback functions. I came across this callback function, callbackPrinter, and its usage in a Node.js project Im working on. Not sure what its doing, specifically in reference to cb.apply(cb, arguments). Im having a hard time wrapping around my head what the whole callbackPrinter is doing.
I need a guidance in reading node.js documentation. Many node functions has " callback" as their last argument. However, the documentation doesnt say what should be the arguments of these callback functions. One such way is using return for continuation instead of calling another function.If a callback is provided, it will be called with the standard Node style (err, result) arguments.Have additional questions about Node.js or want to purchase support?
