reverse-each-word's Introduction

Reverse Each Word

Objectives

Understand the return value of the each method
Use the .collect method
Understand the return value of the .collect method
Use the return of collect for further operation

Instructions

Write a method called reverse_each_word that takes in a string argument of a sentence and returns that same sentence with each word reversed in place.

First solve it using .each Then utilize the same method using .collect to see the difference.

For example:

reverse_each_word("Hello there, and how are you?")
  #=> "olleH ,ereht dna woh era ?uoy"

Hint: You can't use an enumerator on a string, so how can we turn our string into an array?

Hint: How can we reverse each word and return those altered words? Remember that .each returns the original array but other enumerators don't.

reverse-each-word's Issues

update readme

remove front matter, add objectives, better instructions

Following code-along won't pass test.

Prior to starting the Advanced section, the lab states:

Here, we tell our method to return the original array simply by having that array be the last line of the method. Whatever is evaluated last in a method will be it's return value. If you run the test again, you should be passing.

The original array contains "Jim", so how can returning the original array possibly pass the tests, which expect only strings beginning with "T" to be returned?

Reverse Each Word - Possible Test Typo

I believe that there was an error in the specification file. In the second test,
"again," reversed is "niaga,"
with the comma at the end unaffected from the reverse method while in the first test,
"there," reversed was ",ereht".
affected by the reverse. Not noticing a reasoning behind this, I assumed it was a typo
and ended up changing the second test so that "niaga," was ",niaga".

If I missed something, please let me know and I will change the test back and attempt the
lab again.

Add in one more test of another sentence

Just to be explicit about the fact that hard coding isn't the right thing to do :)

Confusing readme with enumerating .each AND .collect

I'm a newb so it was confusing to realize that after passing the tests with .each, I can use the same method with .collect and still have the tests pass. Wasn't sure if I had to create a second method or try to implement .each and .collect in the same method.

Thanks.

Expecting two different outcomes

1st Test inputs "Hello there, and how are you?" and expects "olleH ,ereht dna woh era ?uoy"
2nd Test inputs "Hi again, just making sure it's reversed!" and expects "iH niaga, tsuj gnikam erus s'ti !desrever"

The comma in the first test is reversed but the comma in the second test remains at the end of the word. Two inconsistent expectations.

Issue with 'reverses all words in string w/o reversing order" spec

Hey,

looks like there might be an issue with the 2nd spec for this lab.

I used the solution provided in the solution branch and got the following error:

expected: "iH niaga, tsuj gnikam erus s'ti !desrever"
            got: "iH ,niaga tsuj gnikam erus s'ti !desrever"

The first spec has the comma reverse as part of the word. The second spec has the word reverse but the comma stay in place. There's no way for both of these two pass using the same method.

Suggest updating second spec to:

describe '#reverse_each_word' do
  let(:sentence2) { "Hi again, just making sure it's reversed!" }
  it 'reverses all the words in a string without reversing the order of the words' do
    expect(reverse_each_word(sentence2)).to eq("iH ,niaga tsuj gnikam erus s'ti !desrever")
  end
end

IDE Not Working for this Exercise

rspec issue

The rspec's second test for this lesson seems to have an issue.

It requires the code to produce words in reverse order. The argument the rspec passes is: "Hi again, just making sure it's reversed!" The expected string is: "iH niaga, tsuj gnikam erus s'ti !desrever". As you can see, the last word in the string reversed with the punctuation included ("reversed!" -> "!desrever"), but the second word didn't ("again," -> "niaga,").

The correct output requirement should be "iH ,niaga tsuj gnikam erus s'ti !desrever".
