Iterators Lab

Description

In the iterators lab we will be continuing our exploration of iterators. We have a series of challenges that require you to use the iterators we discussed in class. We will try to use various testing methods to verify that your code is working.

Phase-1

Research the following term and summarize your findings on it two to three sentences:

• higher-order function

Update this README with a description of each of the following and an example you've created:

• forEach: note
• map: note
• filter: note
• reduce: note
• some: note
• every: note

Use the notes provided to help guide you explanation.

Phase-2

• Run npm install from the iterators_lab directory.
• Looks at the tests we've written in the test folder. Run the tests with npm test (also from the iterators_lab directory). They should all fail.
• Get all of the tests to pass by writing the necessary code in src/iterators.js.

Phase-3

Refactor the following code using map to make only one call to the map function versus the two below.

var myNumbers = [ -1, 2, -3, 4, -5, 6];

var square = function(num) {
	return num * num;
};

var sqrRoot = function(num) {
	return Math.sqrt(num);
};


var sqrNumbers = map(myNumbers, square);
var absNumbers = map(sqrNumbers, sqrRoot);
