Description
Welcome to the Crystal Programming Language course on Udemy! In this course, you will learn the fundamentals of the Crystal programming language and how to use it to create powerful, efficient, and concise programs. Crystal is a modern, object-oriented programming language that has a syntax similar to Ruby, making it easy to learn for those familiar with Ruby or other similar languages. With its static type system and focus on performance, Crystal is an excellent choice for building web applications, command-line tools, and many more exciting tools. Throughout this course, you will learn the core concepts of Crystal programming and gain hands-on experience by building various projects.As you progress through this course, you will learn about the key features and characteristics of the Crystal programming language. You will learn how to use Crystal's syntax to write clean and concise code and how to use its powerful type system to ensure your programs are correct and efficient. You will also learn about Crystal's built-in libraries and tools for working with data. By the end of this course, you will be able to use Crystal to solve a wide range of problems and build powerful, efficient, and scalable applications.We will build several applications throughout the span of this course. First we will build a Name Guessing Game, where users would guess a name from a list that we provide. Next, we will build our own version of Rock, Paper, Scissors. Then we will make a simple calculator application. And Finally, we will create a programme that automatically organises our files in different folders for us!Let's get started!
