class and object basics

looked very briefly at closure, need to look more into that

pointing to a variable

harrisonmalone / fibonacci.rb

Created November 21, 2018 10:49

	def fibonacci(n, arr)
	a = 0
	b = 1
	n.times do
	temp = a
	# sets temp to be 0, 1 on the second loop
	a = b
	# sets b to be 1, still 1 on the second loop, 2 on the third loop
	b = temp + b
	arr << a

harrisonmalone / pig_latin.rb

Last active June 23, 2020 22:54

	def pig(sentence)
	array_of_words = sentence.split(" ")
	# here we split every word in the sentence
	pig_array = array_of_words.map do \|word\|
	letter = word[0]
	# here we get the first letter of each word and store it
	array_of_letters = word.split("")
	# here we split each of the words into an array of letters
	array_of_letters.shift
	# we remove the first item from the array of letters

harrisonmalone / demo.js

excellent test for scope and the way javascript works

	function getDemo(demo) {
	const test = function() {
	return demo + ' my friend'
	}
	// an anonymous function is assigned to a variable test
	demo = demo + ' how are you'
	// we do some string concatenation
	// => "hi how are you"
	return test()
	// we return test() which invokes the function, as javascript goes from inner to outer scope demo within this function is "hello how are you" and it's concatenated with " my friend", this value is returned

harrisonmalone / atomic-blonde-mc.js

Last active December 6, 2018 22:20

	// Pick any four digit number and do the following:
	// Rearrange the string of digits to form the largest and smallest 4-digit numbers possible.
	// Take these two numbers and subtract the smaller number from the larger.
	// Suppose we choose the number 8082.
	// 8820−0288=8532
	// 8532−2358=6174
	// 7641−1467=6174
	// It hits 6174 and then stops.
	// Count also how many iterations loops are required to get to this point.
	// Bonus points for recognising what 6174 is.

	const signature = [0,0,1]

	for(x=2; x<10; ++x) {

harrisonmalone / multiples-of-three-and-five.js

Created November 22, 2018 11:05

	// If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23.

	// Finish the solution so that it returns the sum of all the multiples of 3 or 5 below the number passed in.

	// Note: If the number is a multiple of both 3 and 5, only count it once.

	function solution(number){
	const arr = []
	for(i = 1; i < number; i++) {
	arr.push(i)

harrisonmalone / base-10-to-base-2.js

Created November 25, 2018 02:25

	// convert base 10 to base 2

	function baseTenToBaseTwo(baseTenValue) {
	const baseTwoArr = []
	let baseTwoValue = null
	for(let i = 0; baseTwoValue < baseTenValue; i++) {
	baseTwoValue = 2 ** i
	baseTwoArr.push(baseTwoValue)
	}
	// this gives me an array of baseTwoValues (represented in decimal), when the baseTwoValue is greater than what baseTenValue is passed in our for loop ends
