The 2024 State of JavaScript survey offers a comprehensive look into the current landscape of the JavaScript ecosystem. By gathering data from thousands of active developers, the survey underscores significant trends, preferred tools, coding challenges, innovative language features, and favored frameworks and hosting services. The insights derived from this survey are invaluable for anyone seeking to understand the evolving dynamics in the world of JavaScript.
The Rise of AI Code Generators
AI code generators have become pivotal to the daily workflows of countless developers. Despite their growing popularity, it’s noteworthy that 14% of developers indicated they do not use any AI code generators. Among those who do, ChatGPT dominates the scene with a 67% usage rate, followed by GitHub Copilot at 48%. Other notable AI tools include Claude, used by 23% of respondents, and Gemini, with a 14% usage rate.
This widespread adoption of AI tools highlights their profound importance in modern development practices. Tools like ChatGPT and GitHub Copilot have emerged as essential aids, streamlining coding processes and significantly boosting productivity. By leveraging these AI-powered tools, developers can focus on more complex aspects of software development, while routine coding tasks are handled more efficiently.
JavaScript Pain Points
Despite its overwhelming popularity and versatility, JavaScript still presents several challenges for developers. One of the most frequently cited pain points is the lack of static types, with as many as 32% of developers finding this aspect particularly challenging. The introduction of proposals such as type annotations aims to tackle this issue by allowing developers to opt into static types directly within JavaScript. However, the adoption of these proposals has been sluggish, largely because many developers are already satisfied using TypeScript and the associated necessity to forego TypeScript’s compilation step.
Additionally, developers highlighted several features they miss from other programming languages. A standard library (43%), Signals (39%), and a pipe operator (23%) topped the list of desired features. Common deficiencies were also noted in architecture (35%), state management (31%), dependency management (29%), build tools (28%), and performance (24%). These pain points delineate specific areas where JavaScript could improve to better meet the needs of its users and enhance the overall developer experience.
Adoption of New JavaScript Language Features
JavaScript is a living, evolving language, constantly incorporating new features that cater to developers’ needs. Among the more recent additions, the nullish coalescing operator (??), introduced in ECMAScript 11, has been widely embraced, with 85% of developers incorporating it into their code. This operator simplifies the handling of null values in object chains, making JavaScript code both more concise and more readable.
Promise methods such as Promise.allSettled() and Promise.any() have also seen significant adoption, offering developers more efficient ways to handle multiple asynchronous operations. The Array.toSorted() method, adopted by 40% of respondents, has streamlined the common task of sorting arrays. New set methods like union, intersection, and difference, although niche, are gaining popularity among developers, with around 15-16% utilizing them. Another noteworthy feature is Object.groupBy(), which has been adopted by 33% of respondents, providing a powerful tool for organizing objects by properties.
Popular Libraries and Frameworks
The survey provides extensive insights into the libraries and frameworks currently favored by developers, and these preferences can often indicate shifts in the industry. In the front-end framework arena, Angular is making a notable comeback, showing a resurgence in both positive sentiment and overall usage. Following a period of decline, Angular’s revitalization suggests it may be time for developers to reconsider its potential.
Svelte and Vue continue their ascent, boasting high “would use again” sentiment, with 88% and 87% respectively. React remains a significant player, with 43% of developers expressing a positive sentiment towards it. Its widespread familiarity makes React a staple in many development arsenals, despite the burgeoning interest in alternative frameworks.
In the realm of build and repository tools, Vite leads in both usage and developer sentiment, achieving a remarkable 98% retention rate. Pnpm, known for its speed and monorepo support, enjoys a 93% positive sentiment with 42% usage. Another favorite is Esbuild, which has a 91% user approval rating due to its speed and extensive support for various languages and syntaxes. Additionally, SWC, a Rust-based build tool, is valued for its speed and integrated compile/bundle capabilities, earning an 86% positivity rating among developers.
Testing Tools and Meta-frameworks
Testing tools play a critical role in ensuring code quality and reliability, and the survey highlights several popular options within this domain. Vitetest, for instance, has achieved a remarkable 98% retention rate, reflecting its effectiveness and developer satisfaction. Playwright also stands out with a 94% “would use again” rating, making it a favored choice for end-to-end testing. Additionally, Testing Library enjoys a 91% positive sentiment, showcasing its widespread approval and utility among developers.
Meta-frameworks have also gained traction, with several rising stars emerging on the scene. Astro.js has garnered attention, maintaining a strong 94% “would use again” rating despite a slight dip in positive sentiment. SvelteKit is another popular choice, boasting a 90% “would use again” rating, although it has experienced a slight decline in sentiment. Meanwhile, Next.js, a pioneer in the field, retains its status as the most popular meta-framework, holding steady in usage with a solid 68% sentiment, even amidst a sharp decline.
These insights into testing tools and meta-frameworks reveal developers’ preferences and priorities within the JavaScript ecosystem, emphasizing the ongoing pursuit of tools that enhance code quality, streamline development processes, and ensure robust performance.
Hosting Services
Hosting services play a pivotal role in the development and deployment process, and the survey sheds light on the top choices among JavaScript developers. AWS remains the most popular hosting service, used by 44% of respondents, underscoring its dominance in the industry. Vercel follows closely with a significant share of developers opting for its seamless deployment and performance optimization features.
Additionally, GitHub Pages and Netlify are preferred by 38% of developers, each offering accessible and user-friendly deployment options. Cloudflare, with its focus on security and speed, is chosen by 21% of respondents, while Heroku, known for its simplicity and ease of use, is utilized by 19% of developers.
The preferences highlighted in the survey indicate that while AWS continues to lead the hosting service market, other platforms are making significant inroads. The competition among hosting services fosters a landscape where developers have a range of options tailored to their specific needs, encouraging continuous innovation and improvement within the industry.
