Learn the syntax, data types, and operations essential for programming in Scala

Become a Scala Developer

In this module, we will learn Scala from the ground up. This module aims to teach us how to write basic programs, assuming we have no prior knowledge of the language. We will start with a brief introduction to Scala to understand its functionality and applications. We will then move discuss the key features and functions of the language (data types, functions, classes, etc.) in detail. In the end, we will have all the basic knowledge of how to program in Scala.

Learn Scala from Scratch

# Problem

Imagine you have a list of items separated by a comma. You want to print the list vertically, item-by-item to make it easier to read. In other words, you want the compiler to split the string into separate lines at the commas.

# Solution

In Scala, you can use the `split` method to split strings at specific separators such as commas. `split` converts a string into an array of `String` elements and returns that array. For instance, if we have a string `"a,b,c"` and apply the `split` method on it, we would get an array of type `String` containing three elements: `"a"`,`"b"`, and `"c"`.

>An array is a collection of elements of the same data type. For now, you can think of it as a variable that can store multiple values and each value has its own unique place. We will look at arrays in a later [lesson](https://www.educative.io/courses/learn-scala/the-array-collection) in the course.

In the following lesson, you will learn how to split strings in Scala.
