- Timely content updates, automatically refreshing the page or a section of the page
- Interactive maps
- Animated 2D and 3D graphics
- Store useful values inside variables
- Add strings, or operations on a piece of content, to variables
- Events-based responsive code, for example, executing a script based on a click
- Display third-party widgets, like social media feeds, videos, or maps
- Drop-down menus
- Modal windows
- Contact forms
Libraries also usually reduce the amount of code that needs to be written which helps reduce bugs and make a website or application more efficient. Libraries are convenient ways for developers to avoid mistakes, build efficiently, and create reliable applications.
What is an API?
There are two types of APIs: browser APIs and third-party APIs. Browser APIs are built into web browsers while third-party APIs power plug-ins and widgets for websites. Third-party APIs provide code that pulls information from elsewhere on the web.
Browser APIs are able to expose data from the surrounding computer environment and are built into web browsers. Browser APIs enable things like popup windows, geographical location functions, animated graphics, multimedia players, and more.
Third-party APIs enable things like displaying automatically updating social media feeds like Twitter, embedding maps from a third party like Google Maps, or showing a media file from a streaming service like Spotify.
Frameworks provide reusable components for a website or application. You can think of frameworks like the blueprint for building an entire website. It provides structure, shows you which way to go using a preset application flow, and comes with premade tools that help you build each component faster than you could from scratch.
React can be combined with other libraries to create entire applications for the web, mobile devices, or Windows desktop. It’s owned and maintained by Facebook but it remains open-source and free.
React Native is also open-source software created by Facebook. You can create platform-specific versions of each component in your React Native app so that you can build a complex, multi-platform app with one codebase, making debugging more centralized.
Node is free and runs on almost any platform. It works by leveraging an asynchronous, event-driven, non-blocking I/O model to make it lightweight and efficient. Node also offers npm, the world’s largest software registry with over 800,000 code packages for free.
AngularJS is a structural framework for dynamic web applications. AngularJS enables the use of HTML as the template language and extends HTML’s syntax to express your application’s components clearly and succinctly. It’s perfect for building single-page applications.
AnuglarJS was designed to reduce the amount of code developer’s usually have to write for an application like this. It’s free, open-source, and maintained by Google. This library has a vast support network and community. Millions of developers use Angular to build incredibly complex user interfaces.
- Vue.js – pronounced like “view,” this framework is for building user interfaces from the ground up that can be implemented incrementally.
- Backbone.js – Backbone provides structure models for web applications and comes with a rich API collection.
- Ember.js – Ember.js provides templates, server APIs, and app structuring that enable the creation of complex, scalable, single-page application ecosystems.
- MeteorJS – Meteor enables rapid prototyping and cross-platform coding. It’s based on Node.js.
- Polymer JS – Polymer Project is a templating library with modern design principles.
- Webix – Webix is a toolkit created to build rich user interfaces and complex cross-platform web applications.
You could even build websites, web apps, games, or mobile apps without being a web developer full time. Some web developers work as a freelancer part-time, which keeps it fun while still providing an income. Others upskill through their work and use it to work their way up to a promotion.
