The little story behind a side project
"MoR is coming and I could tell sth. about JS inheritance"
"Well, I'm on a train, I could use the time!"
My 'Problem'
I need an interactive, online JS Shell... a nice one please!
One I can iframe inside this presentation!
MY Soltion
online JS Runner
atm.: http://onlinejsrunner.nodejitsu.com
- online, interactive JS shell
- vanilla JS code is executed insight Node.js' VM
- sandboxed
- Technology
- Node.js
- Ace Editor
- => that's about it!
Why you should do side projects
fun
creativity
Famous "Side Projects"
Elon Musk's "Hyperloop"
Some of Google's Services
Einstein's photoelectric effect, Brownian motion and special relativity papers
Incubation
Inspired by Distraction
Why using Inheritance?
- "OOP"
- Easier Developing => better collaboration
- Easier Testing
- JS != class-based
-
it's not Java nor
C++
- Instances (objects) all the way down
-
var a1 = new A() // 1. create (in memory) a1 // 2. copy A.prototype into a1.[[Prototype]] // a1.[[Prototype]] = A.prototype // calling a1.someProperty // I) check if someProperty exists on a1 // II) check if it exists on a1.[[Prototype]] - mdn/[...]/JavaScript/Guide/Inheritance_Revisited

Give me an example
But, how about performance?
package main
import "fmt"
func main() {
fmt.Println("Hello, MoR!")
}
