1. What is ES6
2. Let & Const
   • uses block scoping
   • const cannot be reassigned
   • not hoisted
3. Arrow Functions
   • uses block scoping
   • implied this value assignment
   • no prototype

• The real purpose of arrow functions is to handle the THIS keyword withing nested / callback functions

Notes

1. Sync vs Async
   • JS executes code in a synchronous manner one function at a time one statement at a time
   • JS is single threaded
     • that means only one statement is executed at a time.
   • Asynchronous mean two or more things happening at a time. In JS that means deferring remaining execution of a function
     • We need this because some operation can take be very slow:

Studying for a Tech Interview Sucks, so Here's a Cheat Sheet to Help

This list is meant to be a both a quick guide and reference for further research into these topics. It's basically a summary of that comp sci course you never took or forgot about, so there's no way it can cover everything in depth. It also will be available as a gist on Github for everyone to edit and add to.

Data Structure Basics

###Array ####Definition:

• Stores data elements based on an sequential, most commonly 0 based, index.
• Based on tuples from set theory.

This course is designed as a primer for our JS In-Depth Series of Group Sessions. This is ideal for Design Track students, Developer students struggling to understand JavaScript or students with limited programming experience. We will cover the building blocks of programming with JavaScript. This course assumes little or no experience with JavaScript.First

We have three primary goals today.

1. Walk away with a new mental model for learning and understanding JavaScript or any programming language for that matter.
2. Understand what is a variable
3. Understand what the heck is a function

Anchors in Markdown

To create an anchor to a heading in github flavored markdown. Add - characters between each word in the heading and wrap the value in parens (#some-markdown-heading) so your link should look like so:

1. Set an environment variable called CMDER_ROOT to your root Cmder folder (in my case C:\Program Files (x86)\Cmder). It seems to be important that this does not have quotes around it because they mess with concatenation in the init script.
2. In your IntelliJ terminal settings, use "cmd" /k ""%CMDER_ROOT%\vendor\init.bat"" as the Shell path. The double-double-quotes are intentional, as they counteract the missing double quotes in the environment variable.
