Why is programming language design essential?
The design of programming languages is a critical skill that opens doors to countless areas of knowledge. These languages not only allow us to communicate accurately with computers, eliminating ambiguities inherent in natural languages, but also offer us tools to explore new fields. Take, for example, Wittgenstein's famous quote, "The limits of my language are the limits of my knowledge." Similarly, the programming language you design can expand or limit these boundaries.
Advantages of mastering programming languages
- Accuracy and clarity: Languages eliminate the imprecision of human instructions.
- Knowledge exploration: They work as a magnifying glass to get into different fields.
- Innovation and creativity: Designing a language is a creative act that involves establishing new ways of interacting with machines.
How is a programming language designed?
Designing a programming language involves several key steps. It begins with the creation of a grammar, which is the foundation of the language. This grammar includes:
- Keywords: reserved words that have special meanings.
- Notation and syntax: Specifications that guide how instructions are structured.
- Operators: Mathematical and logical similes that allow various operations.
Implementation: Interpreter or compiler?
The next crucial step is to decide whether to use an interpreter or a compiler, two essential elements that enable a computer to process and execute code:
- Interpreter: Translates and executes the code line by line, ideal for rapid development and scripting languages.
- Compiler: Translates all code into an executable file before running it, which can result in better performance.
What can you expect in the advanced courses?
This introductory course is just the beginning of an exciting journey into the world of programming language design. You'll continue learning through dedicated interpreter and compiler courses, where you'll dive into:
- Software implementation.
- Creation of a unique programming language: Platzi, developed entirely in Spanish.
- Open source innovation: Katán, a project designed to facilitate the learning of programming in Latin America using a familiar syntax based on JavaScript and Python.
So, if you are ready to face challenges that will encourage you to expand your horizons and take your skills to the next level, follow this educational path and become a programming language creator!
