+# Reverse String
+
+The introductory exercise to arrays and strings. Just reverse input string.
+
+This is a typical first program for beginning programming in a new language
+or environment after being able to do simple tasks.
+
+The objectives are simple:
+
+- Write a function that reverses the input string.
+- Run the test suite and make sure that it succeeds.
+- Submit your solution and check it at the website.
+
+If everything goes well, you will be ready to fetch your first real exercise.
+
+## Tutorial
+
+This exercise has two files:
+
+- reverse-string.js
+- reverse-string.spec.js
+
+The first file is where you will write your code.
+The second is where the tests are defined.
+
+The tests will check whether your code is doing the right thing.
+You don't need to be able to write a test suite from scratch,
+but it helps to understand what a test looks like, and what
+it is doing.
+
+Open up the test file, reverse-string.spec.js.
+There is one test inside:
+
+  xit('detects simple reverse string', function () {
+    var subject = new ReverseString('ant');
+    var matches = subject.matches(['tna']);
+
+    expect(matches).toEqual(['tna']);
+  });
+
+Run the test now, with the following command on the command-line:
+
+    jasmine reverse-string.spec.js
+
+The test fails, which makes sense since you've not written any code yet.
+
+The failure looks like this:
+
+    1) Reverse String says reverse string
+       Message:
+          Expected undefined to equal 'tna'.
+
+There's more, but this is the most important part.
+
+Take a look at that first line:
+
+    1) Reverse String says reverse string
+
+Now look at the test definition again:
+
+    it('detects simple reverse string', function() {
+      // ... more code here ...
+    });
+
+Update the code and then run the tests again from the command-line:
+
+    jasmine reverse-string.spec.js
+
+Notice how it changes the failure message.
+
+Then change the implementation in reverse-string.js again, this time to make the test pass.
+
+When you are done, submit your solution to exercism:
+
+    exercism submit reverse-string.js
+
+
+## Setup
+
+Go through the setup instructions for JavaScript to
+install the necessary dependencies:
+
+http://exercism.io/languages/javascript
+
+## Making the Test Suite Pass
+
+Execute the tests with:
+
+    jasmine <exercise-name>.spec.js
+
+Replace `<exercise-name>` with the name of the current exercise. E.g., to
+test the Reverse String exercise:
+
+    jasmine reverse-string.spec.js
+
+In many test suites all but the first test have been skipped.
+
+Once you get a test passing, you can unskip the next one by
+changing `xit` to `it`.
+
+## Source
+
+This is an exercise to introduce users to using Exercism and arrays and strings [https://medium.freecodecamp.org/how-to-reverse-a-string-in-javascript-in-3-different-ways-75e4763c68cb](https://medium.freecodecamp.org/how-to-reverse-a-string-in-javascript-in-3-different-ways-75e4763c68cb)
+
+## Submitting Incomplete Solutions
+It's possible to submit an incomplete solution so you can see how others have completed the exercise.
