Which JavaScript Frameworks Should You Learn in 2023?
The world of web development moves fast. New tools, libraries, and frameworks emerge all the time, making it challenging to know where to focus your energy as a developer. When it comes to JavaScript frameworks, the amount of options can seem overwhelming. But in 2023, there are a handful of clear front-runners that deserve your attention.
As a web developer, learning the right JavaScript frameworks is essential to building modern, interactive web experiences efficiently. Frameworks provide structure and reusable components that greatly speed up development compared to coding everything from scratch with vanilla JS.
But which frameworks give you the best bang for your buck in terms of career opportunities, performance, and developer experience? Let‘s break down the top contenders to help you decide which JavaScript frameworks to learn this year based on your goals.
What are JavaScript frameworks and why should you use them?
First, let‘s clarify what JavaScript frameworks are. A framework is an abstraction that provides generic functionality and structure that you can selectively change by writing additional code. It serves as a foundation that you can build upon.
JavaScript frameworks, therefore, are collections of JS code libraries that provide pre-written JS code to use for routine programming features and tasks. Instead of reinventing the wheel, you can utilize a framework to handle common operations so you can focus on building your unique application.
There are many good reasons to use a JS framework:
- Efficiency: Frameworks come with a lot of pre-built functions and components, dramatically cutting down the amount of original code you have to write.
- Maintainability: Frameworks provide a consistent, organized structure for your code that makes it easier to update and maintain over time, especially as your application scales.
- Collaboration: Since frameworks are widely used, other developers will be familiar with the architecture and able to jump in and understand the code right away.
- Community: Popular frameworks have a large community behind them, which means extensive documentation, tutorials, and support as well as frequent updates.
While there is theoretically nothing you can do with a framework that you can‘t do with pure JavaScript, frameworks will save you a lot of time and headache architecting the perfect foundation for your application.
The top front-end JavaScript frameworks in 2023
Now that we understand what JavaScript frameworks are and why they are useful, let‘s dive into the most prominent front-end frameworks in 2023. These are the tools that help structure the client-side of your application – everything the user sees and interacts with.
React
It‘s impossible to discuss front-end frameworks without talking about React. Facebook developed this front-end library in 2013 and it has dominated the conversation ever since.
React utilizes a component-based architecture and declarative API that makes it easy to reason about your application. Developers create small, reusable components with encapsulated functionality that can be composed to make complex UIs. React components are built with a mix of JavaScript and HTML called JSX.
React‘s virtual DOM is also a key selling point. This in-memory representation of the actual browser DOM enables React‘s fast and efficient rendering. When data in a React component changes, React will determine what changed in the virtual DOM and then make the smallest number of updates possible to the actual DOM.
In addition to Facebook, many large companies use React, including Twitter, Netflix, Airbnb, and Instagram. This robust corporate support along with React‘s huge open-source community means it is a safe bet to continue to innovate and grow in the coming years.
Pros of React:
- Battle-tested and supported by Facebook
- Extensive community and ecosystem of tools and extensions
- Reusable components
- Virtual DOM optimizes performance
- Highly employable skill
Cons of React:
- Steeper learning curve than some other frameworks
- Frequently updated, requiring developers to stay on top of changes
- Integrating React into a traditional MVC framework like Rails requires additional configuration
Vue
Vue has emerged in the past few years as a serious contender to React. With its friendly learning curve, powerful tooling, and flexible architecture, many developers are gravitating towards this progressive framework.
Vue bills itself as an approachable, versatile framework that you can start using right away and incrementally incorporate into an existing project. It features an uncontroversial API design and comprehensive documentation that make it easy for beginners to pick up.
But Vue is not just for beginners. It provides a complete toolset for building complex single page applications including the following:
- Declarative rendering with a simple template syntax
- Reactive state management
- Computed properties
- Lifecycle hooks
- Single file components that encapsulate HTML, CSS and JS in one file
- Client-side routing
- Lightweight state management solution (Vuex)
- Build tooling (Vue CLI)
- Browser devtools extension
With careful consideration for developer experience, strong documentation, and a supportive community, Vue has seen a major uptick in usage. High profile companies using Vue include Nintendo, BMW, Behance, Trustpilot, and GitLab.
Pros of Vue:
- Easiest learning curve
- Flexible and incrementally adoptable
- Simple structure and minimal configuration
- Excellent documentation
- Blazing fast
- Rising popularity
Cons of Vue:
- Smaller ecosystem of plugins and tools compared to React
- Fewer job opportunities than React or Angular
Angular
Angular is the grandfather of modern JavaScript frameworks. Google first released this MVC framework in 2010 and it quickly became the go-to for building complex single page applications.
Angular uses TypeScript, a superset of JavaScript, to enable a powerful type system and object-oriented features. It follows a strict pattern of dependency injection, decorators, and services that can feel foreign to non-Angular developers.
Because it is a complete, opinionated framework, Angular has a lot of concepts to learn and pieces that need to work together. However, if you like having guardrails and a prescribed "Angular way" of doing things, you will appreciate this framework.
Some notable companies using Angular include Google, Microsoft Office, Samsung, Deutsche Bank, and Forbes.
Pros of Angular:
- Opinionated structure helps enforce consistency
- Dependency injection increases testability
- Two-way data binding
- Built-in support for forms and validation
- Integrates well with other Microsoft tools like .NET
- Long-term Google support
Cons of Angular:
- Steep learning curve
- Rigid structure can feel confining
- Performance can suffer if not optimized
- Verbose syntax
- Migrating between major versions can be painful
Svelte
Svelte is a new kind of framework that has been gaining popularity for its simplicity and stellar performance. Rich Harris developed Svelte to provide a more lightweight alternative to heavier frameworks like React and Angular.
The key innovation of Svelte is that it is a compiler rather than a traditional front-end framework. Instead of shipping a bulky library to the browser, Svelte compiles your application to pure JavaScript at build time. The result is incredibly performant, lightweight applications.
Svelte provides a simple API for building components with minimal boilerplate. It supports a template syntax similar to Vue and offers all the reactivity you would expect from a modern front-end framework. Svelte is also flexibile enough to be incorporated incrementally into an existing application.
With its focus on developer experience and performance, Svelte is definitely a framework to watch in 2023. It is still a younger framework so it may not have as many job opportunities yet, but its usage is growing. Companies using Svelte include Spotify, Square, The New York Times, Facebook, and Rakuten.
Pros of Svelte:
- Simple and intuitive API
- Truly reactive
- Super fast performance
- Smaller bundle sizes
- No virtual DOM overhead
- Easier to learn than React or Angular
Cons of Svelte:
- Smaller ecosystem of tooling and support
- Not as many job opportunities…yet
- Smaller community
Back-end JavaScript frameworks
JavaScript has become a popular choice for back-end programming thanks to environments like Node.js. Node allows you to run JavaScript on the server side to handle business logic, interact with databases, and serve up APIs.
To make Node development more efficient, several frameworks have emerged to provide additional features and structure:
Express.js
Express is the most popular Node framework and provides a minimal, unopinionated set of features for building web applications and APIs. It is known for its simplicity, flexibility and scalability.
Next.js
Next.js is a lightweight framework for static and server-side React applications. It provides automatic code splitting, server-side rendering, a powerful build pipeline, and other optimizations to make React apps as performant as possible.
Nuxt.js
Nuxt is a progressive framework based on Vue that makes it easy to create universal or statically generated Vue apps. Similar to Next, it offers an intuitive set of tools for efficient Vue development.
Nest.js
Nest is a newer TypeScript framework for building scalable Node applications. It is known for its extensible architecture, powerful CLI, and dependency injection features.
Which frameworks should you learn?
With so many frameworks to choose from, which one should you focus your energy on learning? The answer depends on your specific goals and interests.
Front-end developer
If you want to specialize in front-end web development, React is the safest bet in terms of job opportunities and community support. However, Vue is an excellent alternative if you want something with a gentler learning curve.
Consider Angular if you will be working in a Microsoft-heavy ecosystem or in an enterprise environment that prioritizes convention and stability. Svelte is a newer option but its simplicity and performance gains make it a compelling choice.
