Answering the Front-end developer JavaScript interview questions to the best of my ability.

Explain event delegation

Sometimes you need to delegate events to things.

Explain how this works in JavaScript

This references the object or "thing" defined elsewhere. It's like "hey, thing I defined elsewhere, I'm talkin' to you."

Explain how prototypal inheritance works.

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

Clarify and agree on the scope of the system

User cases (description of sequences of events that, taken together, lead to a system doing something useful)
- Who is going to use it?
- How are they going to use it?

To create a Table

	create table risk_clos_rank(
		id_num int IDENTITY(1,1) NOT NULL,
	    username nvarchar(100),
	    datetime_of_decision DATETIME
	);
	
	CREATE TABLE TheNameOfYourTable (
 ID INT NOT NULL IDENTITY(1,1),

	1. Write poly-fill of Object.create and explain why it worked:

	if(typeof Object.create != "function") {
	Object.create = function(param) {
	var Fun = function(){};
	Fun.prototype = param;
	return new Fun();
	}
	}

	import Ember from 'ember';

	export default Ember.Controller.extend({
	appName: 'Ember Twiddle'
	});

	To initialise a new git repository
	git init

	To download a repository from a website
	git clone https://github.com/tutorialzine/awesome-project.git

	To remove commits from github.
	git log
	to find out the commit you want to revert
	git push origin +7f6d03:master

	All challenges. I lied a bit, these are actually in reverse chronological order, to make it less annoying to use on mobile devices.
