Unlike many other languages, Rust has two main string types: String (a heap-allocated string type) and &str (a borrowed string, which does not use extra memory). Knowing the difference and when to use each is vital to understand how Rust works.

Arrays are constructs provided by most programming languages to access a group of same objects via an index. In some languages, the types must be the same (Java), while in others (JavaScript, Python) multiple types can be in an array.
