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

# Introduction

Like Lists, Vectors are another immutable collection of sequence type. They differ in the fact that Lists are linear while Vectors are indexed. What this means is that if you want to access a central element in a List, the compiler has to start from the beginning and linearly progress through the List until it finds the element you are trying to access. However, when you want to access a central element in a Vector, the compiler can directly go to that index and access the element in constant time.

While Lists should be used when you only plan to manipulate the head element (first element), Vectors provide efficient access when you want to manipulate elements beyond the head. 

# Creating a Vector

Vectors can be created using the `Vector` keyword followed by `()`.

In the following lesson, you will be introduced to Vectors.
