Libraries and frameworks are both sets of pre-written code, but libraries are smaller and tend to be used for more specific use cases. A library contains a collection of useful code, grouped together for later reuse. The goal of a spain number data library is to allow developers to achieve the same end goal while writing less code to get there.
Let's take the example of JavaScript, the language, and jQuery, a JavaScript library. Instead of writing, say, ten lines of JavaScript code, the developer can get the condensed, pre-written version of the jQuery library — saving time and effort.
A framework contains ready-made components and tools that allow developers to write code faster, and many frameworks also contain libraries. It provides developers with a structure to work with, and the framework you choose to work with will largely dictate how you build your website or app, so choosing a framework is a big decision. Some popular frameworks include Bootstrap, Rails, and Angular.
The easiest way to understand libraries and frameworks is to imagine that you are building a house. The framework provides the foundation and structure, as well as the instructions or guidelines for completing the tasks. Let's say you want to install a furnace in your house: you can buy the components separately and build it from scratch, or you can buy a pre-assembled furnace from the store. Just like building a website, you can write the code from scratch, or you can take pre-written code from a library and simply plug it in.
Other development tools
One thing a web developer also does is use text editors, such as Atom , Sublime or Visual Studio Code , to write their codes; a web browser, such as Chrome and Firefox ; and one crucial tool: Git !
Git is a version control system where developers can store and manage their code. As a web developer, it’s inevitable that you’ll make frequent changes to your code, so a tool like Git that allows you to track these changes and revert them if necessary is extremely valuable. Git also makes it easy to work with other teams and manage multiple projects at once. Git has become such an essential in the world of web development that it’s considered bad practice not to use it.
Another extremely popular tool is GitHub , a cloud-based interface for Git. GitHub offers all the version control functions of Git. But it also comes with its own features such as bug tracking, task management, and project wikis. Git hub not only hosts repositories, but also provides developers with a comprehensive set of tools, making it easier to learn best practices for coding. It is considered the place to be for open source projects and also provides a platform for web developers to showcase their skills.

6. What does it take to become a web developer?
A career in web development is challenging, financially rewarding, and has a lot to offer in terms of job security. The Bureau of Labor Statistics predicts that employment for web developers will grow by 15% between 2016 and 2026 — much higher than the average — web development is the 8th best career in technology based on salary and employment rate.
The first step towards a career in web development is to learn the necessary languages, libraries, and frameworks. You will also need to familiarize yourself with some of the tools mentioned above, as well as common terminologies.
In terms of languages you want to learn, it all depends on whether you want to focus on frontend or backend development, so all web developers should be proficient in HTML, CSS, and JavaScript.
