In the early days of web development, it wasn’t uncommon for one person to do everything. The job title was often referred to as “webmaster,” “web designer,” or “web developer.” These days, there is often more specialization because the web has become so much more advanced. The different areas of focus are usually broken down into three categories: front-end, back-end, and full-stack.

These languages are also categorized as client-side languages because the browser is also referred to as the client. The client in this context is not someone you’re doing work for!
Back-end developers are responsible for the “behind the scenes” functionality such as submitting payment information when making an online purchase or when you’re logging into an account.
Back end developers work with languages that run on a server, such as Python, PHP, C#, Ruby or Java. Back-end developers also work with database technologies, such as MySQL or MongoDB. You don’t need to know all of these languages to be a backend developer and many specialize in a couple of languages and may have some familiarity with others.
