Traditionally known for its role in web development, JavaScript has — much to the surprise of many — also proven invaluable in developing applications that use large language models (LLMs). In this article, we’ll explore five leading tools for AI engineering, highlighting some essential resources for developers wanting to incorporate LLMs into their projects. We’ve chosen them for their unique capabilities in simplifying complex AI processes and enhancing model training, catering to both experienced AI engineers and JavaScript devs who are new to AI.

Python or Mojo are much more straightforward languages for AI engineering, however, a market already valued at $142 billion in 2023 offers plenty of opportunities for professionals with different skill sets. Advanced AI capabilities will become increasingly accessible to a wider range of developers over time; but even now, a variety of JavaScript tools exists that can aid in the development, training, and deployment of AI models.

Let’s take a closer look at five JavaScript tools that can help facilitate and improve AI engineering.

1. TensorFlow.js

As a JavaScript adaptation of the renowned TensorFlow library created by Google, TensorFlow.js caters specifically to the web and Node.js environments, to bring machine learning capabilities directly to browsers and server-side applications.

One of the key strengths of TensorFlow.js is its ability to run machine learning models directly within the browser. This functionality is particularly valuable for apps requiring real-time AI functionality — such as LLMs to enable swift, server-independent processing.

Its Node.js compatibility is equally important for server-side applications that need to leverage powerful computing resources essential for the heavy computational demands that LLMs require.

The library’s seamless integration with existing JS apps makes it a preferred choice for many devs, as it allows them to incorporate AI features into their web apps without extensive re-engineering or the need to learn a new language. TensorFlow.js also offers a range of pre-trained models to simplify the initial steps in LLM integration.

When it comes to AI engineering with JavaScript, TensorFlow.js is a compelling resource in a developer’s toolkit. It not only lowers the barrier to entry for adding sophisticated AI features (like LLMs) into applications but also supports the creation of real-time, interactive AI experiences on the web — opening up new avenues for user engagement and app functionality as a result.

2. AI.JSX (

AI.JSX, developed by Fixie, is a dynamic framework designed for building conversational AI-powered apps using JavaScript and JSX that’s specifically tailored for React-based projects.

It stands out among AI engineering tools for its robust support for prompt engineering and its easy integration with external APIs. It represents a significant leap forward in developing interactive, AI-driven applications, particularly for those that are focused on conversational AI.

A core feature of AI.JSX is its unique ability to dynamically construct user interfaces at runtime, which is a feature known as GenUI. Here, devs can provide a set of React components to the LLM, allowing the creation of UIs that are interactive while being adaptive to the application’s needs.

Fixie’s DocsQA allows the model to ground itself in various sources of truth, such as URLs, documents, PDFs, and even video and audio files. This enhances the model’s understanding and responsiveness, to ensure the AI is interactive, informed, and accurate.

AI.JSX also extends the capabilities of applications through its tools feature, which focuses on enabling action-oriented functionalities through APIs, to allow end-users to complete tasks more efficiently and effectively.

3. ConvNetJS

ConvNetJS is a JavaScript library that’s designed to enable deep learning directly in the browser or in Node.js environments, making it accessible and convenient for JavaScript devs of all skill and experience levels.

ConvNetJS stands out for its ability to implement deep learning architectures, including convolutional neural networks, without needing external dependencies or specialized software.

Theoretically, recognition-based libraries like ConvNetJS could be used to develop security-focused applications for threat intelligence enrichment, helping to identify things like unauthorized access, patterns characteristic of malware, phishing attempts, debit card fraud, identity theft, and other forms of digital crime that leave a searchable trace.

One of the primary advantages of this library is its ease of use, which provides a straightforward API that allows developers to define, train, and deploy neural networks relatively easily. This simplicity is particularly valuable for JS devs who may not have extensive experience in deep learning, but are trying to incorporate advanced AI features into their applications.

This library facilitates the creation and integration of neural networks that are capable of understanding and generating human language, which is crucial for apps like chatbots, automated content generation, and language translation services. Its neural network models can be trained on large datasets to allow them to capture the nuances of human language and improve the overall responsiveness and accuracy of AI-driven apps.

4. Brain.js

Brain.js is a notable entry on our list, as it offers a streamlined and approachable way to implement neural networks in JavaScript, catering to both browser and Node.js environments. A key potential application of Brain.js is automating processes like text analysis, PDF document merging, document conversion, image analysis, and, overall, tackling any task that involves crunching copious amounts of data.

Brain.js was designed with simplicity and ease of use in mind, making it an ideal choice for JavaScript developers who may not have an extensive background in machine learning. The library provides a straightforward API that lets you quickly create, train, and deploy neural networks.

This powerful tool plays a critical role in LLM development by enabling the creation of neural networks capable of processing and interpreting large volumes of text data. By training neural network models on extensive text datasets, Brain.js helps capture the subtleties of human language, thereby enhancing the effectiveness and accuracy of AI applications.

5. Tabnine

Tabnine is an AI-powered code completion assistant that significantly enhances the coding experience. Specifically, it accelerates the broader development process while actively maintaining code integrity.

Tabnine’s AI learns from the codebase and suggests relevant code snippets, function completions, and even entire blocks of code based on natural language comments. This level of support is invaluable in managing the intricate details involved in AI application development.

Tabnine’s integration capabilities are notable, as it works seamlessly with a range of popular IDEs and code editors, including Visual Studio Code, IntelliJ IDEA, and plenty of others. This type of robust compatibility helps ensure that devs can access Tabnine’s AI-assisted coding features without disrupting their existing workflows.

Another significant aspect of Tabnine is its commitment to maintaining code privacy and security. The tool has been carefully designed to respect the privacy of developers’ code, ensuring that the code you’re working with remains private and secure.

Making AI Engineering Easy with JavaScript

Each tool we’ve highlighted here today brings its own unique strengths to the table, and they collectively signify the essential role that JavaScript can play in AI development.

JS stands out in AI engineering, particularly for its seamless integration in both browser and server-side environments, offering unparalleled flexibility. Unlike Python, which is often confined to server-side operations, JavaScript enables real-time, interactive AI applications directly within web browsers.

This allows developers to create more dynamic and responsive AI-driven experiences, leveraging the full-stack capabilities of JavaScript to bridge the gap between backend AI algorithms and frontend user interactions.
