Let’s explore!

What Are the Different Types of Programming Languages?

Every programming language is different. While each programming language has its unique syntax, how it’s written, run, and compiled can change everything.

Many developers prefer to work with certain types of languages. It’s also a lot easier to migrate between similar languages, so the first programming language you learn matters.

So what are the different types of programming languages? There’s a difference between scripting and programming languages? Let’s take a look.

  • Programming languages can be just about anything, but they’re often best for software development as they can be used on various platforms and tend to be compiled rather than interpreted. Most programming languages are intended for software development, to develop programs you download and run on your device.
  • Scripting languages are just the opposite. They’re often interpreted, which means their code runs on the fly rather than going through a compiling process inside a program. Web development languages are often scripting languages.
  • Markup languages aren’t precisely programming languages, but they’re used for web development. These are human-readable tags used to format a document.
  • Web development languages are specialized for creating websites, either in the frontend or backend.
  • Frontend (or client-side) languages change a website in the user’s browser. For instance, clicking something on the website and producing an animation would result from frontend programming like CSS, HTML5, and JavaScript. It’s usually a combination of all the above languages.
  • Backend (or server-side) languages change a site from the server or application layer. For example, submitting form data, or changing something in the database, is backend programming.

You should also note that many people just use “programming languages” to refer to all coding languages as a whole. A scripting language is a specialized programming language, but not all programming languages are scripting languages.

Not all languages below are programming languages in the strictest sense, but they’re all used for coding.

It’s time to dive in!
