Scala allows you to declare variables in two ways: 'var' for mutable variables and 'val' for immutable variables, ensuring clear intent in code.
In Scala, basic data types include Int, Double, Boolean, String, and Char, which showcase the language's versatility for various programming tasks.
Control structures in Scala, including if-else, for loops, and while loops, are expressions that return values, enhancing the language's functional programming capabilities.
Scala's collections like Arrays, Lists, Tuples, Maps, and Sets provide powerful data handling options, allowing for efficient data manipulation and retrieval.
