Reverse Function

Create a function to reverse a string here with the name reverse.ts.

Functionality Steps

The function's job is to take in a single string argument reverse it and return it as a string.

• You could easily use String.prototype.split() to get all the words individually in a single array.

"hello world".split(" ");
// Returns => ["hello", "world"]

• Reverse them using Array.prototype.reverse().

["hello", "world"].reverse();
// Returns => ["world", "hello"]

• Use Array.prototype.map() to split the letters in each word and reverse them too.

["hello", "world"].map(word, () => {
  return word.split("").reverse();
  // Returns => [ [ 'd', 'l', 'r', 'o', 'w' ], [ 'o', 'l', 'l', 'e', 'h' ] ]
});

• Join them back using Array.prototype.join() with a single space.

const wordsArray = ["hello", "world"].map(word, () => {
  return word.split("").reverse().join("");
  // Returns => [ 'dlrow', 'olleh' ]
});

return wordsArray.join(" ");
// Returns => "dlrow olleh"

Best Practices

• Made tests before writing the function.
• Followed naming convention (camelCase).
• Followed recommended style (2 space indentation).
• Didn't nest any loops.
• All tests are passing after implementing the feature.

Please keep in mind, the words from the argument might have not only spaces but punctuations too.

Feel free to use the following regex. You can add more regex but don't edit the existing ones.
