daronwolff / array_inverter.js

Last active May 19, 2016 18:10

Javascript - Invert array position elements manually. I created this little code to my friends in Kwan

	"use strict";
	if (!Array.prototype.reverseOrder) {
	Array.prototype.invertir = function() {
	var inverted = [];
	for (var i = this.length - 1; i >= 0; i--) {
	inverted[this.length - (i + 1)] = this[i];
	}
	return inverted;
	}
	}

daronwolff / isArray.js

Created May 19, 2016 23:05

This little script is used to test if an array is really an array or not.

	"use strict";
	if (Array.prototype.isArray === undefined) {
	Array.prototype.isArray = function (value) {
	return Object.prototype.toString.apply(value) === "[object Array]";
	};
	}
	/*
	Examples
	*/
	Array.isArray({}); //false

Write two binary functions "add" and "mul", that take two numbers and return their sum and product

	"use strict";
	var add = (function(a){
	return function (b){
	return a + b;
	}
	});
	var mul = (function(a){
	return function(b){
	var total = a * b;
	return total;

daronwolff / factorial.js

Created May 20, 2016 16:41

Javascript Factorial function

	function factorial(n) {
	"use strict";
	var result = 1;
	while (n > 1) {
	result *= n;
	console.log(result);
	n -= 1;
	}
	}

daronwolff / exercise_3.js

Created May 20, 2016 19:34

Write a function that takes an argument and returns a function that returns that argumen

	"use strict";
	function identify(x) {
	return function(){
	return x;
	}
	}

	var idf = identify(3);
	idf(); // 3

daronwolff / exercise_4.js

Created May 20, 2016 20:31

	var add = (function(a) {
	return function(b) {
	return a + b;
	}
	});


	var mul = (function(a) {
	return function(b) {
	var total = a * b;

daronwolff / exercise_5.js

Created May 20, 2016 21:07

Write a function that takes a function and an argument, and returns a function that can supply a second argument add3 = curry(add,3); add3(4); // 7

	var add = (function(a) {
	return function(b) {
	return a + b;
	}
	});


	var mul = (function(a) {
	return function(b) {
	var total = a * b;

daronwolff / exercise_6.js

Created May 20, 2016 22:03

Write a methodize, a function that converts a binary function to a method

	function add(a,b) {
	return (a + b);
	}
	function methodize(func) {
	return function(y){
	return func(this,y);
	}
	}
	Number.prototype.add = methodize(add);
	(2).add(3) // 5

daronwolff / exercise_7.js

Last active May 20, 2016 22:15

Write a DEmethodize, a function that converts a method to a binary function Example demethodize(Number.prototype.add)(5)(6) // 11

	function demethodize(func){
	return function(that,y){
	return func.call(that,y);
	}
	}
	var add = (function(a) {
	return function(b) {
	return a + b;
	}
	});

daronwolff / exercise_8.js

Created May 20, 2016 22:31

Write a TWICE, function that takes a binary function and returns a unitary function that passes its arguments to the binary function twice Example var double = twice(add); double(11); // 22 var square = twice(mul); square(11); // 121

	var add = (function(a) {
	return function(b) {
	return a + b;
	}
	});
	var mul = (function(a) {
	return function(b) {
	var total = a * b;
	return total;
	}
