Challenge 4: Scrub Forbidden Words

Objective

Develop the scrub function that takes a string of text and an array of forbidden words. The function will replace any forbidden word in the text with a string of lowercase "x" characters, each "x" replacing one letter of the forbidden word. The modified text is then returned from the function.

Function

function scrub(text, forbidden)

Parameters

• text: A string representing the text to be scrubbed.
• forbidden: An array of strings, each a forbidden word to be replaced in the text.

Requirements

1. Replace each word in text that is included in the forbidden array with a string of "x" characters of equal length to the forbidden word.
2. Ensure no punctuation is used in the text.
3. If text is empty or there are no forbidden words, return the original text.

Examples

Example 1

let result = scrub("out of the silent planet", ["of", "silent"]);
console.log(result);

Expected Output:

"out xx the xxxxxx planet"

Example 2

let result = scrub("the ghost of the navigator", ["the"]);
console.log(result);

Expected Output:

"xxx ghost of xxx navigator"

Example 3

let result = scrub("lost somewhere in time", []);
console.log(result);

Expected Output:

"lost somewhere in time"

Example 4

let result = scrub("aces high", ["high", "aces", "hearts"]);
console.log(result);

Expected Output:

"xxxx xxxx"

Example 5

let result = scrub("", ["high", "aces"]);
console.log(result);

Expected Output:

""

Hint

Utilize array methods like push, split, indexOf, and join to effectively transform the text.
