Hello, Adventurer! Today, we will learn about splitting and joining strings — two vital operations for processing textual data in Go. Are you ready? Let's start this journey!

In this lesson, we will use the following imports:

In Go, the strings.Split function cuts a string into several pieces based on a delimiter, which is a character that separates words. It returns a slice containing these divided parts. Look at this example:

Here, we have a sentence cut into separate words using the strings.Split() function, with a space as the delimiter. The results are stored in the slice words.

The strings.Join() function merges a slice of strings back into a single string using a given delimiter. You can think of it as the inverse of the strings.Split() operation. Here's how it works:

In the example given above, we took a slice of words and combined them into a single string, using a space as the delimiter.

Both strings.Split() and strings.Join() can be used together to manipulate texts such as rearranging sentences. Let's take "I love programming" and rearrange it to "programming love I":

Here, we first split the sentence into words. Then, we swapped the positions of the first and last words before finally joining them back into a new sentence.

Moreover, strings.Join is flexible — it allows you to specify all parts to join one by one:

It proves to be quite handy at times!

Great job, Explorer! You've learned how to split and join strings in Go using strings.Split() and strings.Join(). Now, you will try your hand at some exercises to reinforce your newly acquired skills. Are you ready to explore further? Let's proceed!
