- 3. Why Node? ● Asynchronous ● Robust ● Blazingly FAST ● Javascript / Browserify ● Largest growth year over year ● Largest frontend tool belt @thanpolas #SKGNode
- 4. Asynchronous ● Event Based Development ● Real Time Applications ● Single Threaded ● Non Blocking I/O @thanpolas #SKGNode
- 5. Robust ● Very small footprint / stack ● Hundreds thousand production installations ● Easily Scalable ● Every major company is deploying node ○ Yahoo ○ Paypal ○ eBay ○ LinkedIn @thanpolas #SKGNode
- 6. Blazingly Fast ● Superior V8 engine under the hood ● 2x speed compared to Threaded langs ○ PHP ○ Java ○ Ruby ● Wins both in RPS and Response Time @thanpolas #SKGNode
