The Development of the C Language* Dennis M. Ritchie Bell Labs/Lucent Technologies Murray Hill, NJ 07974 USA dmr@bell-labs.com ABSTRACT The C programming language was devised in the early 1970s as a system implementation language for the nascent Unix operating system. Derived from the typeless language BCPL, it evolved a type structure; created on a tiny machine as a tool to improve a meager progr

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
Today we’re excited to announce the release of TypeScript 5.8! If you’re not familiar with TypeScript, it’s a language that builds on top of JavaScript by adding syntax for types. Writing types in our code allows us to explain intent and have other tools check our code to catch mistakes like typos, issues with null and undefined, and more. Types also power TypeScript’s editor tooling like the auto

Our Experience Porting the YJIT Ruby Compiler to RustIn this post, I want to give a nuanced perspective on our experience porting YJIT from C to Rust. I'll talk about the positives, but also discuss the things that we found challenging or suboptimal in our experience. Last year, my team at Shopify implemented YJIT, a new Just-In-Time (JIT) compiler for CRuby, which was recently upstreamed as part

[EN] Writing a Compiler is Surprisingly Easy (part 1)
Part 1: expressions, arithmetic Part 2: statements, control flow Ever since I was a teenager I wanted to create my own systems programming language. Such a programming language would certainly have to be compiled to native code, which meant I'd have to write a compiler. Even though I managed to write several half-working parsers, I'd always fail at the stage of generating assembly code, as the tas

Introduction The story behind this article is very simple, I wanted to learn about new C++20 language features and to have a brief summary for all of them on a single page. So, I decided to read all proposals and create this “cheat sheet” that explains and demonstrates each feature. This is not a “best practices” kind of article, it serves only demonstrational purpose. Most examples were inspired

V8 Torque is a language that allows developers contributing to the V8 project to express changes in the VM by focusing on the intent of their changes to the VM, rather than preoccupying themselves with unrelated implementation details.

Following up from the last post, there is a lot more we need to cover. This was intended to be the post where we talk exclusively about benchmarks and numbers. But, I have unfortunately been perfectly taunted and status-locked, like a monster whose “aggro” was pulled by a tank. The reason, of course, is due to a few folks taking issue with my outright dismissal of the C and C++ APIs (and not showi
