The Profane

We need to update the /api/validate_chirp endpoint to replace all "profane" words with 4 asterisks: ****.

1. Assuming the length validation passed, replace any of the following words in the Chirp with the static 4-character string ****:

• kerfuffle
• sharbert
• fornax

Be sure to match against uppercase versions of the words as well, but not punctuation. "Sharbert!" does not need to be replaced, we'll consider it a different word due to the exclamation point.

2. Finally, instead of the valid boolean, your handler should always return the cleaned version of the text in a JSON response, even if nothing changed:

Example Input

{
  "body": "This is a kerfuffle opinion I need to share with the world"
}

Example Output

{
  "cleaned_body": "This is a **** opinion I need to share with the world"
}

Run and submit the CLI tests.

Use an HTTP client to test your POST requests.

I'd recommend breaking the bad word replacement into a separate function. You can even write some unit tests for it!

Here are some useful standard library functions:

• strings.ToLower
• strings.Split
• strings.Join
