## Javascript Problems – Create my own Array.prototype.map() method – myMap()

In this exercise, I will create my own map method – myMap(). According to MDN Developers Network, “The map() method creates a new array with the results of calling a provided function on every element in the calling array.” I have used the same sample data and functions as I did for the myForEach problem.  […]

## Javascript Problems – Create my own Array.prototype.filter() method – myFilter()

The purpose of this exercise is to create my own Array.prototype.filter() method – myFilter().  On line 2, I add a new myFilter() method, which takes in a function as an argument, to the array object.  I loop through each item in the array that called the method, and on line 6 determine if the function has […]

## Javascript Problems – Create my own Array.prototype.forEach() method – myForEach()

The purpose of this exercise is to create my own Array.prototype.forEach() method – myForEach(). According to the MDN Developers page for Array.prototype.forEach(), “The forEach() method executes a provided function once for each array element”. I use the same sample data sets as I did or the myMap() method.  Whereas myMap() modifies each element in the […]
