Let’s talk about how a website works before getting into the nitty-gritty of back-end vs. front-end web development.
How a Website Works
Think of your experience when you visit a restaurant. You sit in the dining area and interact with the service staff, or waitstaff. The restaurant might have nice decorations and an overall great atmosphere. You might order something through the waitstaff, with which they go to the kitchen and order your request. While you’re waiting for your food, you don’t see the cooks preparing it, but you know your order is being worked on. When your food is hot and ready, the waitstaff brings it from the kitchen to your table.
Your experience with a website is much like your experience at a restaurant. The front-end aspect of the analogy is everything you see or interact with when at the restaurant. While you’re there, you see the well-decorated dining area and interact with the waitstaff. The back-end part of this analogy is the behind the scenes aspect of the restaurant, or the kitchen. While you can’t see the kitchen, you know your order of food is being fulfilled there.
When you visit a website, there are specific elements to the page that you can see and interact with—images, text, videos, colors, fonts, drop-down menus, sliders, forms, etc. All these things make up the front-end portion of the website. The back-end is everything you can’t see or interact with, such as servers, databases, operating systems, and APIs.
How the Front-End and Back-End Interact
Keep thinking about the restaurant analogy. You give your food order to the waitstaff, they carry it back to the kitchen, put in your order, the cooks prepare your food, and the waitstaff brings you your finished order. Your interactions and experience on a website isn’t much different from that at a restaurant. When you request something on the front end (aka waitstaff), that request is sent to the back end (aka kitchen). The back end fulfills your request (aka food order) and sends the data back to the front end (aka waitstaff). As a result, you have your desired action. It’s a beautiful thing.
Programming for Front-End vs. Back-End Web Development
Both front-end and back-end development require different skills and focuses, or programing languages. While there are hundreds of programming languages for web development, there are specific languages for frontend and backend web development that are more popular and important to know than others.
