How to split a string

Use the split_whitespace() method to break a string into words or split() with a delimiter to break it at specific characters.

let text = "hello world wonderful world";
for word in text.split_whitespace() {
    println!("{word}");
}

To split by a specific character like a period, use split('.') and handle the resulting iterator:

let novel = String::from("Call me Ishmael. Some years ago...");
let first_sentence = novel.split('.').next().unwrap();
println!("{first_sentence}");

Splitting a string means breaking a long line of text into smaller pieces based on spaces or specific characters. You use this when you need to process individual words or sentences separately, like counting how many times a word appears. Think of it like cutting a loaf of bread into slices so you can eat them one by one.
