问题 Having installed io.js aside node.js, I notice the following oddity trying to upgrade node-gyp. When trying out npm install -g node-gyp I get the following at the top of the output: /usr/local/lib/iojs-v3.3.1-linux-x64/bin/node-gyp -> /usr/local/lib/iojs-v3.3.1-linux-x64/lib/node_modules/node-gyp/bin/node-gyp.js node-gyp@3.0.3 /usr/local/lib/iojs-v3.3.1-linux-x64/lib/node_modules/node-gyp I am a bit concerned that io.js installation, or the hack used for upgrading it, have somehow altered the

问题 I see that Node.js has added i/o to its capabilities, does that mean that it's more async now, or it is using the same concurrency model as before? Also, I thought Node was on v8, why have they rolled back to v4? 回答1: io.js was a fork of the node.js codebase that was advancing differently than the core node.js. io.js was its name and is not directly related to some large set of I/O capabilities.

The forks I am aware of are: The official nodejs release iojs - I guess it's now deprecated since it's rejoined the official nodejs, but it's still of interest JXcore - a fork that supports multiple CPUs/core; multiple JS engines including V8, Mozilla's SpiderMonkey, and Microsoft's ChakraCore; and packaging of js apps so npm doesn't need to be

Difference between Events and Functions?

I am new to Node, and I am struggling to understand the main difference between Events and Functions. Both need to be triggered, so why do we need an Event at all if we have to trigger it anyway? How is it different than having a Function triggered? Example code: var events = require('events'); var eventEmitter = new events.EventEmitter(); eventEmitter.on('event1', function () { console.log('Event 1 executed.'); eventEmitter.emit('event2'); }); eventEmitter.on('event2', function() { console.log('Event 2 executed.'); }); eventEmitter.emit('event1'); console.log('Program Ended.'); We can achieve
