Web development is the process of creating websites and applications for the internet or a private network known as an intranet.
Front-end web development involves a combination of programming languages, frameworks, and design skills to create a website. Using these tools, front-end developers can build interactive websites that meet a client’s specific needs and preferences.
Front-end developers focus on a website’s visual elements, including text colours and styles, images, buttons, navigation menus, and the ability for users to change their settings. They also make sure that a website’s content appears correctly on different devices (e.g., desktops, smartphones, and tablets), allowing it to adapt to the device’s display size.
Another important tool for front-end developers is a web server, which allows them to access and manipulate data from a database. These servers communicate with back-end servers, which send information to the front-end of a website in response to a request from a user. Then, the front-end developer uses logic created by back-end developers to retrieve this data and send it to the right user.
This process is critical for the online experience, which enables people to get information instantly and easily. This is why the Internet has become a key part of our everyday lives.
In addition to coding, front-end developers need to have problem-solving skills to help fix technical issues in the website creation process. This includes communicating with designers and back-end developers who may not have much technical knowledge.
Front-end developers can work in a variety of industries and earn a range of salaries, depending on their skill level and experience. However, the job outlook is positive as more and more companies invest in digital experiences. In fact, the Bureau of Labor Statistics projects that web developer jobs will grow by 15% between 2016 and 2026.
Back-end web development is the coding that allows websites to function and respond to user requests. It consists of server-side programming languages, database management, business processes, and data architecture.
While front-end developers are primarily concerned with the design and aesthetics of a website, back-end web developers are more focused on how the site actually works. These developers use programming languages to create the software that powers the applications that run on the website, and their work is never seen by users.
Similarly, back-end web development includes working with databases that store information in a persistent form and reduce the load on the server CPU. Back-end developers also write APIs, which are standardized ways of communicating with servers and other software components. They can also create libraries for other programmers to use.
Another important skill that back-end developers need is a solid understanding of the basic algorithms of computer software. These are the underlying processes that allow computers to solve problems, such as sorting algorithms, searching algorithms, string parsing, matching, hashing, and recursive algorithms.
A back-end developer needs to know these skills well enough to build an effective web application. They can learn these basics through a formal degree program, a coding boot camp, or a combination of both.
It’s possible to learn these skills on your own, though they can be more difficult if you don’t already have experience in programming. It’s recommended to get a formal four-year degree in computer science to ensure you have the right foundation for your career.
Then, you’ll need to master a variety of programming languages to become a competent back-end developer. Commonly used server-side languages include Ruby, Python, and PHP. You can also learn database management languages, such as SQL, which are widely used for storing information in databases.
Finally, it’s important to have a good understanding of version control systems like Git. These software tools keep track of code changes and allow developers to restore old versions of their code, which can be a lifesaver when trouble arises. Having these skills will help you get the most out of your career as a back-end developer.
