Frontend vs.​ backend

Frontend

Frontend development manages everything that users visually see on their browser or application. Frontend developers are responsible for the look and feel of a site – they engage in analyzing code, perfecting the design, and debugging applications to ensure a seamless user experience.

Backend

Backend development refers to the server-side of an application, and everything that communicates between the database and the browser. The primary responsibilities of a backend developer are making updates, changes, and monitoring the functionality of a site. This type of web development usually consists of three parts:

• A server
• An application
• A database.

Code written by backend developers ​communicates information from the database to the browser.

• Frontend refers to the client-side​​ of the application.

• It is a part of the website that users can see and interact with.

• It typically includes everything that attributes to the visual aspects of websites.

• It forms the basis of what users can touch and experience on their web browsers.

• The essentials of frontend development include CSS, HTML, and JavaScript.

• Backend refers to the server-side of the application.

• It constitutes everything that happens behind the scenes.

• It generally includes a web server that communicates with the database to serve requests that the frontend presents.

• It is the brain of the website and is never visible to the end-users​.

• The essentials of backend development include Ruby, Python, Java, .NET, etc.
