Web development generally refers to the tasks associated with the development of websites intended to be hosted via an intranet or the Internet. The web development process includes, among other things, website design, web content development, client-side or server-side scripting, and network security configuration.
Web development is the coding or programming that makes a website work, according to the owner's requirements. It mainly deals with the non-conceptual aspect of website building, which includes coding and writing markup.
A web developer or programmer is a person who takes a web project, which has been thought and thought through by a client or design team, and turns it into a website. They do this by writing complicated lines of code. To write them, they use different languages with a specificity and a usefulness for each one of them.
Web developers have a pretty tough job because they have to take a language we understand, like English, and translate it into a language a computer understands, like Python or HTML.
As you can imagine, it will take a lot of time and effort to learn different programming languages and their uses. Different types of developers specialize in different areas, which means that large web projects are usually a collaboration between several different developers.
