What's the Difference Between the Front-End and Back-End

Frontend Development

The frontend of a website is what you see and interact with on your browser.Also referred to as “client-side”, it includes everything the user experiences directly: from text and colors to buttons, images, and navigation menus.

The front-end developer creates interaction and user experience with scripts embedded in a site’s HTML. Everything a visitor to your site sees, clicks, or uses to input or retrieve information is the work of the front-end developer who creates client-side software that brings the site’s design to life.
Front-end web development, also known as client-side development is the practice of producing HTML, CSS and JavaScript for a website or Web Application so that a user can see and interact with them directly.

Backend Development

The backend is the portion of the website you don’t see. It’s responsible for storing and organizing data, and ensuring everything on the client-side actually works. The backend communicates with the front-end, sending and receiving information to be displayed as a web page. Whenever you fill out a contact form, type in a web address, or make a purchase (any user interaction on the client-side), your browser sends a request to the server-side, which returns information in the form of frontend code that the browser can interpret and display.
A back-end developer is a type of programmer who creates the logical back-end and core computational logic of a website, software or information system.
