Programming languages are sets of instructions used to instruct computers to perform tasks.
They are categorized into High-Level, Low-Level, and Hybrid languages.
High-Level languages like Python, JavaScript, and Ruby are easier to learn and understand.
Low-Level languages like C, C++, and Swift focus more on machine understanding and are compiled.
Hybrid languages like Java and C# combine compilation and interpretation benefits.
Popular backend programming languages include Python, JavaScript (Node.js), C#, Java, and Go (Golang).
Python is versatile, JavaScript can be used on the backend with Node.js, C# is Microsoft's language, Java is known for portability, and Go is simple and fast.
Choosing a programming language depends on personal preference, job requirements, and desired outcomes.
Writing clean, scalable, and maintainable code is crucial regardless of the chosen language.
The author personally prefers Python and JavaScript but acknowledges preferences may change.
