/* # Palindrome

​

For this challenge, a palindrome is a string that is the same backwards and forwards, ignoring spaces, punctuation, and capitalization. Some examples of palindromes are `madam`, `racecar`, `2020-02-02`, `Never odd or even`

​

## Initial Challenge

​

Write a function that will accept an array of strings, and return an array of any strings that are palindromes. The snippet below shows an example input, and the expected output:

​

```

Input: ['madam', 'goodbye', 'racecar', 'able was I ere I saw elba', 'development']

Output: ['madam', 'racecar', 'able was I ere I saw elba']

```

​

## Advanced Challenge

​

Does your function work correctly with the following input?

​

```

["Madam, I'm Adam", 'A man, a plan, a canal - Panama', 'Not a palindrome', 'racecar', 'Able was I ere I saw Elba', '2020-02-02']

``` */
