Daily Issue #130 | Subscribe to DS | Daily Sandbox Pro

Hello Developers!

Discover hidden JavaScript tricks to refine your coding skills, explore OpenAI's Realtime API for voice-enabled AI using WebRTC, and see how four AI tools stack up when generating UI from the same prompt. A professional editor reveals telltale signs of ChatGPT-generated content, while a deep dive into AI’s role in coding warns against over-reliance, emphasizing the importance of critical thinking and problem-solving in development.

Dive in and keep coding!

JavaScript capabilities you might not know about - In this article, I’d like to share some JavaScript life hacks that might help you understand the nuances of the language and improve your code. Overall, the article is aimed at juniors and mid-level developers; seniors might find it boring, but everyone is welcome 🤗

Getting Started: OpenAI Realtime and WebRTC - OpenAI's Realtime API enables live voice and text interactions, allowing developers to integrate AI-driven speech assistants into their applications. This tutorial walks through setting up a voice-enabled AI using WebRTC, covering session management, establishing a connection, handling real-time audio, and integrating OpenAI's model for a seamless experience.

I tested 4 AI tools to generate UI from the same prompt - Tired of AI tool lists that don’t prove their worth, I decided to test nearly 20 design tools myself. Many failed, but I’ve narrowed it down to the ones that actually deliver results. This article shares my prompt, the tools that worked, and my honest feedback on their performance.

I’m a Professional Editor and These Phrases Tell Me You Used ChatGPT - This article explores the fine line between using AI as a writing tool and relying on it to generate low-quality, repetitive content. The author, a former editor-in-chief, shares insights on AI’s strengths, the pitfalls of overuse, and the telltale phrases that reveal ChatGPT-written articles. The key takeaway: great writing is clear, concise, and intentional—something AI alone can’t replicate.

AI Is Making Us Worse Programmers - AI is reshaping software development, but not always for the better. Over-reliance on tools like ChatGPT is eroding fundamental skills like debugging, architecture, and creative problem-solving. To stay ahead, developers must resist intellectual shortcuts, question AI-generated code, and use AI as a critique tool rather than a crutch. The best programmers won’t just prompt—they’ll still think.

Today, I was checking out the OpenAI API docs, and to my surprise, there were tons of new features. It’s been a few months since I last looked, but the sheer number of updates was staggering. The most exciting one is the Realtime API, which lets you communicate with a GPT-4o-class model in real time using WebRTC or WebSockets. It supports both text and audio input/output, live transcriptions, and even includes session tokens along with client and server event handling.

Fine-tuning has also seen major improvements, with OpenAI now offering full management for fine-tuning jobs, making it easier to train models on custom datasets. Another big change is the Projects feature, which allows better organization management, including creating, updating, and archiving projects. You can also upload files, and all related threads will have access to them. As for Assistants, they’re still in beta with no major updates yet.

One thing that really stood out to me was OpenAI’s new Cookbook, a collection of high-quality code snippets and configuration examples for different use cases. The level of detail and clarity is impressive, and it reinforces my point from yesterday about DeepSeek leveraging OpenAI’s documentation and libraries.

• prompts-js - async alternatives to browser alert() and prompt() and confirm().

• retry - A JavaScript utility for retrying async methods that reject errors (written by Nicholas C. Zakas)

• stricli - Build complex CLIs with type safety and no dependencies

• blendy - 🧈 Smoothly transition one element into another with just a few lines of code.
