                This is my technical interview cheat sheet. Feel free to fork it or do whatever you want with it. PLEASE let me know if there are any errors or if anything crucial is missing. I will add more links soon.
              
          
    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.


## Traversals.js
// - - - Pre Order - - -
const PreOrder = (tree, cb) => {
  cb(tree.val);

  if (tree.left) {
    PreOrder(tree.left, cb);
  }

  if (tree.right) {
    PreOrder(tree.right, cb);

## permute.js
var permute = function(nums) {
    nums = nums.join("").split(""); //convert to strings so you can concat values
    var counter = 0;
    var rounds = nums.length;
    var fixed;
    var result = [];

    function recurse(nums,counter,rounds) {
        if(rounds) {
            rounds--;

## bst.js
//all nodes to the right and above current can be added to the value of the current node
//***How can I think about this? I try thinking about it visually and it's very slow to draw out the call stack
//is there a more effective way ? Often I get lost in the call stack.

var sum = 0;
var convertBST = function(root) {

if(root === null) return null;
convertBST(root.right);
root.val += sum;

## LongestPalindrome.js
//create freq obj for each letter, iterate over
  //if even, increment a counter of its value
  //if odd > 1, increment counter value - 1
  //if odd = 1, dont count it.
  //at end you can add 1 to account for letters that have freq of one. (create variable for this)
    //can only happen once (assuming letter w/ freq of 1 exists.)
  //ex's. '' - 0, abc - 1, abbc - 3, aaabb - 5, zzz - 3, aaabbcde- 5

var longestPalindrome = function(s) {
    var freq = {}, longest = 0, hasOdd = false;

## code.js
/*
The first solution I thought of was:
turn both strings into arrays
sort both strings (js native sort method)
loop through the arrays
when the letters aren't equal return the letter in the t array
or if they're all equal return the letter at the end

But using the sort method means the time complexity at worst > O(n).

                Angular vs Backbone vs React vs Ember notes
              
          
    Note: these are pretty rough notes I made for my team on the fly as I was reading through some pages. Some could be mildly inaccurate but hopefully not terribly so. I might resort to convenient fiction & simplification sometimes.
My top contenders, mostly based on popularity / community etc:

Angular
Backbone
React
Ember

Mostly about MVC (or derivatives, MVP / MVVM).
