Modulo

Wolfram defines the modulo operation as "m mod n is the remainder on division of m by n. The sign of m mod n for real m, n is always the same sign of n."

Python has a true modulo operator.

-5 % 2
# => 1

Array Workout

Find min & max within an array

Given an array write a program that returns the largest element. Then try the smallest element.

// construct an array of values
var arr = [25, 101, 66, 10, 99];

Functions Workout

Functions represent computations to be performed.

A return statement causes a function to cease execution and return a value to the caller. If no value is specified the return statement will return the undefined value.

The difference between parameters and arguments. Parameters are used in function definition.

function loop(array) { // array is a parameter that defines what is passed into the function

Migrate Functions

Migrate building a simple array

var arrayBuilder = function(size) {
  // create an empty array to store our values
  var array = [];
  
  // iterate the value of the argument

FizzBuzz

function fizzbuzz(times) {
  for (var i = 1; i <= times; i++) {
    // you must test for both first
    if (i % 5 === 0 && i % 3 === 0) {
      console.log('FizzBuzz');
    } else if (i % 5 === 0) {
 console.log('Buzz');

Choo Notes

Models are where state is contained and methods for updating the state are defined. All logic is centralized within models.

Views are functions that return a DOM tree of elements.

choo's tagged template string html builder is the yo-yo library — A tiny library for building modular UI components using DOM diffing and ES6 tagged template literals.
