What does the Replace() function specifically do in string manipulation?

1. Only replace titles in text strings

2. Change numbers in strings to letters

3. Replace all target instances of a string specified

4. Return the length of the string

The correct answer is: Replace all target instances of a string specified

The Replace() function is designed to search for a specific substring within a string and replace all instances of that substring with a new string that you specify. This means that every occurrence of the target substring is modified in the resulting string, making it a powerful tool for string manipulation tasks where you need to update, clean, or transform text data consistently. This function does not limit its operation merely to specific types of strings, such as titles or numbers; rather, it can operate on any string and can replace occurrences regardless of their nature. Additionally, while some functions return information like the string length, the Replace() function specifically focuses on modifying the contents of the string itself rather than providing meta-information about it.
