When should you prefer chomp vs chop, and when should you avoid it?

In Perl, both chomp and chop are used to remove characters from strings, but they do so in different ways. Understanding when to use each function is crucial for effective string manipulation.

When to Use chomp

The chomp function is used to remove the newline character from the end of a string. It is particularly useful when you are reading input from a file or from user input, as it cleans up the string without affecting any other characters.

When to Use chop

The chop function, on the other hand, removes the last character from a string, regardless of what that character is. This can be useful when you need to remove a specific character or simply the last character of a string.

When to Avoid chomp and chop

Avoid using chop if you specifically need to keep the final character. For example, it should not be used indiscriminately when manipulating strings where the last character is important, such as in structured data or certain formats. Similarly, be cautious with chomp if the string may not contain a newline at the end; using it in such cases won't cause issues, but it won't have the desired effect either.
