Today we are excited to announce the availability of TypeScript 6.0! If you are not familiar with TypeScript, it’s a language that builds on JavaScript by adding syntax for types, which enables type-checking to catch errors, and provide rich editor tooling. You can learn more about TypeScript and how to get started on the TypeScript website. But if you’re already familiar with the language, you ca

Object Structure in JavaScript EnginesFrom a developer's perspective, objects in JavaScript are quite flexible and understandable. We can add, remove, and modify object properties on our own. However, few people think about how objects are stored in memory and processed by JS engines. Can a developer's actions, directly or indirectly, impact performance and memory consumption? Let's try to delve i
All JavaScript and TypeScript Features of the last 3 years
TypeScript as envisioned by Stable DiffusionThis article goes through almost all of the changes of the last 3 years (and some from earlier) in JavaScript / ECMAScript and TypeScript . Not all of the following features will be relevant to you or even practical, but they should instead serve to show what’s possible and to deepen your understanding of these languages. There are a lot of TypeScript fe
1 Introduction Compilers, assemblers and similar tools generate all the binary code that processors execute. It is no surprise then that these tools play a major role in security analysis and hardening of relevant binary code. Often the only practical way to protect all binaries with a particular security hardening method is to have the compiler do it. And, with software security becoming more and
Introduction to Go 1.21 The latest Go release, version 1.21, arrives six months after Go 1.20. Most of its changes are in the implementation of the toolchain, runtime, and libraries. As always, the release maintains the Go 1 promise of compatibility; in fact, Go 1.21 improves upon that promise. We expect almost all Go programs to continue to compile and run as before. Go 1.21 introduces a small ch

Introduction[*] I was honored by the selection of this paper as the 7th best web research in PortSwigger’s top 10 web hacking techniques of 2025. Some time after publishing my previous research on Next.js, I was left with a feeling of unfinished business. That work had sparked my curiosity, and I sensed that this framework still had more secrets to unveil. So, I grabbed my pickaxe once more and de
Today we are excited to announce the Release Candidate (RC) of TypeScript 6.0! To get started using the RC, you can get it through npm with the following command: npm install -D typescript@rc TypeScript 6.0 is a unique release in that we intend for it to be the last release based on the current JavaScript codebase. As announced last year (with recent updates here), we are working on a new codebase
When a single-page application needs to fetch data from a remote source, it needs to do so while remaining responsive and providing feedback to the user during an often slow query. Five patterns help with this. Asynchronous State Handler wraps these queries with meta-queries for the state of the query. Parallel Data Fetching minimizes wait time. Fallback Markup specifies fallback displays in marku

Now we apply that shape as a mask on an image using the CSS Paint API. Since we are dealing with a blobby shape, it’s suitable to consider square elements (height equal to width) instead, where the radius is equal to half the width or height. Here we go using a CSS variable (N) to control the number of points. I highly recommend reading the first part of my previous article to understand the struc

What's new in Swift 5.5? Async/await, actors, throwing properties, and more! Swift 5.5 comes with a massive set of improvements – async/await, actors, throwing properties, and many more. For the first time it’s probably easier to ask “what isn’t new in Swift 5.5” because so much is changing. In this article I’m going to walk through each of the changes with code samples, so you can see how each of
React Best Practices – Tips for Writing Better React Code
By Jean-Marc Möckel Two years ago, I started to learn and use React. And today I'm still using it at my day job as a Software Developer and in my own side projects. During that time I've come across a lot of "typical" issues. So I searched around and found some best practices that I've integrated into my workflow, and I've come up with things that have made my life or my team members' lives easier
The sad state of property-based testing libraries Posted on Jul 2, 2024 Property-based testing is a rare example of academic research that has made it to the mainstream in less than 30 years. Under the slogan “don’t write tests, generate them” property-based testing has gained support from a diverse group of programming language communities. In fact, the Wikipedia page of the original property-bas
Computer history, restoring vintage computers, IC reverse engineering, and whatever The New York Times recently introduced a new daily puzzle called Pips. You place a set of dominoes on a grid, satisfying various conditions. For instance, in the puzzle below, the pips (dots) in the purple squares must sum to 8, there must be fewer than 5 pips in the red square, and the pips in the three green squa
You can create actions to perform tasks in your repository. If you're making a custom action, it will require a metadata file that uses YAML syntax. Note You can build Docker container, JavaScript, and composite actions. Actions require a metadata file to define the inputs, outputs, and runs configuration for your action. Action metadata files use YAML syntax, and the metadata filename must be eit
Primitive Recursive Functions For A Working Programmer Aug 1, 2024 Programmers on the internet often use “Turing-completeness” terminology. Typically, not being Turing-complete is extolled as a virtue or even a requirement in specific domains. I claim that most such discussions are misinformed — that not being Turing complete doesn’t actually mean what folks want it to mean, and is instead a stand
Building a TypeScript CLI with Node.js and Commander - LogRocket Blog
Editor’s note: This post was updated on 13 April 2023 to include instructions on how to use GitHub Actions to publish the Node.js CLI to npm so it will be accessible to all users. The command line has thousands of tools, such as awk, sed, grep, and find available at your disposal that cut development time and automate tedious tasks. Creating a command line tool in Node.js isn’t very complicated, t
This article was discussed on Hacker News. Every passing decade, it seems as if the task of implementing a new programming language becomes easier. Parser generators take the pain out of parsing, and can give us informative error messages. Expressive type systems in the host language let us pattern-match over a recursive syntax tree with ease, letting us know if we’ve forgotten a case. Property-ba

Django for Startup Founders: A better software architecture for SaaS startups and consumer apps
In an ideal world, startups would be easy. We'd run our idea by some potential customers, build the product, and then immediately ride that sweet exponential growth curve off into early retirement. Of course it doesn't actually work like that. Not even a little. In real life, even startups that go on to become billion-dollar companies typically go through phases like: Having little or no growth fo
