To answer this question, I will focus on the code snippets that are actually provided.

Looking at the `Html Preparation Code` section, I see that there is an example string:
```
example = ",;Example 1,,;Example 2,,;Example 3,,;Example 4"
```
This string appears to contain semicolons (`;`) and commas (`,`), which are separated by semicolons.

Now, let's look at the individual test cases. There are three test cases:

**Test Case 1: `split + join`**
```javascript
var result = example.split(',,;').join('; ');
```
This code splits the input string into an array of substrings using commas and semicolons as separators, and then joins the resulting array back into a single string with semicolons in between.

**Test Case 2: `replace`**
```javascript
var result = example.replace(/,,;/g, '; ');
```
This code uses a regular expression to replace all occurrences of the pattern `,,;` with a single semicolon (`;`) in the input string.

**Test Case 3: `replaceAll` (not shown)**

This test case is not complete, as the replacement string is missing.

To answer the question, I would need more information about the expected output or behavior for each test case. Can you please provide that?
