AI Code Generators: A Growing Trend in Software Development
The Rise of AI-Assisted Coding
Artificial Intelligence (AI) tools are rapidly becoming a common part of the software development process. In fact, the 2025 State of JavaScript survey reveals that AI code generators are now an integral part of many developers’ workflows. Despite some concerns, AI has not completely replaced the need for manual coding. Instead, it has enhanced developers’ productivity by automating certain aspects of the coding process.
According to the survey, 67% of developers reported using ChatGPT for code generation, while 48% opted for GitHub Copilot. Other AI tools like Claude (23%) and Gemini (14%) are also gaining popularity. While some developers still hesitate to rely fully on AI for coding tasks, others have embraced these tools as valuable assistants that help streamline their work.
Why AI Tools Matter
AI tools such as ChatGPT and GitHub Copilot assist in tasks like code completion, debugging, and even documentation. These tools help reduce development time, allowing developers to focus more on higher-level problem-solving and less on repetitive tasks. As AI code generators continue to improve, their ability to suggest or even write code from scratch will likely become even more sophisticated, making them a more indispensable tool for developers.
JavaScript Pain Points: What Developers Find Challenging
The Call for Static Types in JavaScript
Despite JavaScript’s flexibility, many developers still face frustration with its lack of static types. The 2025 survey highlights that 32% of developers continue to find the absence of static types a significant pain point. Static typing helps catch errors early in the development process, making it easier to debug and maintain code. This is particularly important for large-scale applications where managing complex data structures and ensuring consistency across the codebase can be a challenge.
One solution that has been gaining traction is TypeScript, a superset of JavaScript that adds static typing capabilities. However, developers have raised the question: Should JavaScript adopt static typing directly? If this happens, it could eliminate the need for TypeScript’s compilation step, streamlining the process even further. While this change may take time, it’s clear that a significant portion of the JavaScript community is ready for this improvement.
Other Pain Points in JavaScript Development
While static typing is one of the most discussed issues, developers also pointed out other pain points that hinder their productivity. For instance, 43% of developers wish JavaScript had a more comprehensive standard library, which is a feature present in many other programming languages. The absence of a robust standard library can lead to reliance on third-party libraries, which often introduce unnecessary complexity.
Additionally, developers expressed frustration with JavaScript’s handling of certain features. 39% mentioned the lack of signals (a way to handle asynchronous events), and 23% wished for a built-in pipe operator, which would allow for more functional programming patterns. These features, while not essential for every use case, could provide significant improvements to JavaScript’s flexibility and expressiveness.
Architecture, State Management, and Dependency Issues
Another significant category of pain points revolves around the architecture and state management of JavaScript applications. With 35% of developers citing deficiencies in architecture, it’s clear that building scalable and maintainable JavaScript applications remains a challenge. State management is a related issue, with 31% of developers reporting difficulties in managing the state of large applications.
Dependency management is also a problem, with 29% of developers noting that handling dependencies in JavaScript projects can be cumbersome. Build tools (28%) and performance concerns (24%) also continue to hinder developers’ progress, highlighting that JavaScript, while powerful, still has areas for improvement.
The Latest JavaScript Features: What Developers Are Using
The Adoption of Nullish Coalescing
One of the standout features in recent versions of JavaScript is the nullish coalescing operator (??), which was introduced in ECMAScript 11. This operator allows developers to easily handle null or undefined values, improving the readability and maintainability of the code.
According to the survey, 85% of respondents are now using the nullish coalescing operator in their projects. This operator simplifies what would otherwise be verbose checks for null or undefined values. For example, instead of writing:
javascriptCopyEditif (report && report.machine && report.machine.status) {
machineStatus = report.machine.status;
} else {
machineStatus = "No thinking machines!";
}
With nullish coalescing, you can replace this with:
javascriptCopyEditlet machineStatus = report?.machine?.status ?? "No thinking machines!";
This concise syntax helps reduce boilerplate code and improves code clarity, which explains its widespread adoption.
Promise.allSettled() and Promise.any(): Handling Asynchronous Operations
Another useful feature in JavaScript is the addition of Promise.allSettled() and Promise.any(), both of which are designed to handle asynchronous operations more efficiently. These methods provide developers with ways to deal with promises that may resolve or reject without causing unnecessary errors.
According to the survey, 47% of developers use Promise.allSettled(), while 43% use Promise.any(). These methods are particularly useful when dealing with multiple asynchronous operations that may not all succeed. For example:
javascriptCopyEditPromise.allSettled([fetchData(), fetchAnotherData()])
.then(results => {
// Handle both successful and failed promises
});
In cases where you just need one successful promise, Promise.any() provides an elegant solution:
javascriptCopyEditPromise.any([fetchData(), fetchAnotherData()])
.then(result => {
// Handle the first successful promise
});
These newer methods simplify asynchronous programming and reduce the complexity of error handling.
Array.toSorted(): A Simple Way to Sort Arrays
Sorting arrays is a common operation in programming, and JavaScript makes it easier than ever with the introduction of the Array.toSorted() method. This method, used by 40% of survey respondents, provides a straightforward way to sort arrays without the need for extra code or complicated sort functions.
Here’s an example:
javascriptCopyEditconst spiceInventory = [
{ spice: 'Melange', quantity: 500 },
{ spice: 'Sapho', quantity: 100 },
{ spice: 'Rakis', quantity: 200 }
];
// Sort by quantity in descending order
const sortedInventory = spiceInventory.toSorted((a, b) => b.quantity - a.quantity);
The array is sorted naturally based on the sorting function provided, allowing for clean and easy-to-understand code.
Set Methods: Union, Intersection, and Difference
JavaScript’s Set data structure provides a powerful way to manage unique values. With the introduction of Set.union(), Set.intersection(), and Set.difference(), developers now have even more tools at their disposal for working with sets.
- Set.union(): Combines two sets into one.
- Set.intersection(): Returns the common elements of two sets.
- Set.difference(): Returns the elements that are unique to one set.
Example:
javascriptCopyEditconst set1 = new Set([1, 2, 3]);
const set2 = new Set([3, 4, 5]);
const unionSet = set1.union(set2); // Set {1, 2, 3, 4, 5}
const intersectionSet = set1.intersection(set2); // Set {3}
const differenceSet = set1.difference(set2); // Set {1, 2}
While only 16% of respondents have used Set.union(), it’s clear that these methods are gaining traction as developers realize the power and simplicity they offer for handling sets.
Object.groupBy(): Organizing Data with Ease
The introduction of Object.groupBy() allows developers to group objects based on specific properties, making data organization easier and more efficient. This method, used by 33% of developers according to the survey, simplifies the task of categorizing data.
Example:
javascriptCopyEditconst books = [
{ title: "The Hitchhiker's Guide to the Galaxy", genre: "Science Fiction" },
{ title: "Pride and Prejudice", genre: "Romance" },
{ title: "The Lord of the Rings", genre: "Fantasy" },
{ title: "1984", genre: "Science Fiction" }
];
const booksByGenre = Object.groupBy(books, (book) => book.genre);
This results in the following grouping:
javascriptCopyEdit{
"Science Fiction": [
{ title: "The Hitchhiker's Guide to the Galaxy", genre: "Science Fiction" },
{ title: "1984", genre: "Science Fiction" }
],
"Romance": [
{ title: "Pride and Prejudice", genre: "Romance" }
],
"Fantasy": [
{ title: "The Lord of the Rings", genre: "Fantasy" }
]
}
This feature reduces the need for complex code to group or categorize objects manually.
