Welcome! In this lesson, we'll explore Scala's string manipulation capabilities, focusing on methods like split, mkString, trim, and how to perform type conversions. Scala's powerful string methods simplify text processing, enhancing the readability and efficiency of our code.

Working with strings often requires breaking them into smaller sections or 'tokens'. In Scala, the split method achieves this by dividing a string into an array of substrings using a specified delimiter. If no delimiter is provided, you can split by whitespace using regular expressions.

In the example above, we see that split divides the sentence into words. You can opt for different delimiters, such as a comma.
