-------- 4/23/17 --------- I learned various tools and software for web development, such as Git and Github, terminal commands, etc. Update and install different development toolkits (emmit, rubocop, Sublimelinter...) Use git to keep track of changes when writing code (need to commit for changes) Learned to get unstuck when coding. These include: (step 1 to 5 I already know) 6. Decompose problems (divide the puzzle into smaller problems) 7. Ask specific questions.

-------- 4/24/17 ---------

------ Day 2 -------

The rails' "button_to" can add a button to the html file instead of using the tag. The rails' "link_to" method can be used to conveniently add a link to html file.

------ Day 3 ------- We can use redirect_to to navigate to a page after a form is submitted.

flash: a built-in Rails method (put in in layouts/application.html.erb) to pass information in one page to another.

-----5/14/2017----- It is better to use Recipe.where ("prep_time > ?", 10) than Recipe.where("prep_time > 10") because sometimes user does not enter 10 as prep_time, but some strings or something else. That's why we need to check user's input first. localhost:3000?sort=prep_time => sort the index page by prep_time (asc order) 85% of jobs applicants got jobs through referrals.

-----5/15/2017----- Normalization: reduce repeatative rows in Database associations. Foreign key: one-to-many relationships

----05/21/2017----- Met Luke today: learn to talk to people naturally => it may lead to a job opportunity. Learned how to use Screencast and iMovie to create a video blog cast.

----05/23/2017----- IMPORTANT! Remember to capitalize model name rails g model CartedProduct product_id: integer order_id: integer Remember controller names are plural rails g controller CartedProducts

JSON: JavaScript Object Notation

---------6/5/2017------------------ jbuilder is built by default by Rails show.jbuilder.json => build a JSON show page json.array! @employees.each do |employee|

end

Aside from jbuilder, we can also use responder, RABL, active_model_serializer

	------ Day 1 -------

	create database on Rails:
	rails db:create

	rails generate model Recipe title:string chef:string ingredients:string directions:string image:string prep_time:integer

	CRUD:
	Read:
	ModelName.all ==> return an array of hashes of all items in the database

	---------6/12/2017------------
	Javascript
	It can return unexpected results
	> 5 + "2" => "52"
	> 5 - "2" => 3

	parseInt("342")
	342.toString()
	type comparison: 5 === '5' => false (strict)
	5 == '5' => true (loose)

	--------6/18/17---------
	JavaScript is asyncronous: it does not wait for a function to finish before starting another one.

	Ruby runs code from top to bottom (synchronous)
	JavaScript runs code asynchronously.

	anonymous function: a function with no name
	function() {
	console.log('Hello');
	}

	Rails form tag:

	datetime_local_field_tag

	add:
	/* global angular */ if having problem with Linter

	Unit Testing
	It is better to write modular codes
