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.

// what's hoisted
// var carName (just the variable name is hoisted)
// driveCar (whole function is hoisted because driveCar is a function declaration)
// var parkCar (just the variable name is hoisted because parkCar is a function expression)
console.log(carName);
// -> undefined
driveCar(carName);
// -> driving undefined
parkCar(carName);
// -> TypeError: undefined is not a function
