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

Remember when we learned about [literals](https://www.educative.io/courses/learn-scala/strings-and-other-literals) at the beginning of this course? They are defined as fixed values appearing directly in the source code. Literals don't need to be named, they can simply be used directly. 

In the previous [lessons](https://www.educative.io/courses/learn-scala/summation-with-higher-order-functions), we needed to create multiple small functions for our summation functions to execute. But we only required the functionality of those functions. Naming them was an extra unnecessary step in that scenario.

What we need are something similar to literals. Functions that do not need to be named as their functionality is only required for a single instance. 

Scala provides a solution known as anonymous functions.

Anonymous functions are function literals which don't require a name. They can be passed as-is to a higher-order function.

# Syntax

Let's look at the syntax for an anonymous function. 

In this lesson, you will be introduced to anonymous functions and learn their syntax.
