JavaScript programmers have many good tools to choose from—almost too many to keep track of. In this article, I discuss 10 text editors with good support for developing with JavaScript, HTML5, and CSS, and for documenting with Markdown. Why use an editor for JavaScript programming instead of an IDE? In Read more…
Node.js 18, the latest version of the popular JavaScript runtime, has been released, bringing enhancements in cryptography and turning on an experimental fetch API by default. However, prebuilt binaries for 32-bit Windows are not yet available. Introduced April 19 and available from the Node.js website, Node.js 18 improves security with Read more…
Deno 1.21 has been released. This latest upgrade to the JavaScript/TypeScript runtime features improvements to the REPL (read-evaluate-print loop) and a move away from default type-checking. The Deno REPL is a tool for prototyping and trying out new things. With Deno 1.21, an 1-–eval-file flag can be used with the Read more…
Developers of the Deno JavaScript and TypeScript runtime are exploring the possibility of JavaScript containers—and the JavaScript sandbox itself—as a higher-level alternative to Linux containers. In a blog post this week, Ryan Dahl, who spearheaded development of both the Deno and Node.js JavaScript runtimes, cited JavaScript as the “universal scripting Read more…
Deno Deploy, a serverless service for running JavaScript, TypeScript, and WebAssembly applications at the edge, has moved closer to general availability with the release of Beta 4, which includes a paid service plan. General availability of Deno Deploy is eyed for the third quarter of this year. Announced May 24, Read more…
Deno is championed as a more-secure alternative to the popular Node.js JavaScript runtime. The 1.0 version of the Deno runtime, which leverages the V8 JavaScript engine and was built using Rust, arrived in May 2020. Node.js founder Ryan Dahl even spearheaded Deno’s development, which now has more than 83,000 stars Read more…
A recent upgrade to Deno, the JavaScript and TypeScript runtime positioned as a rival to Node.js, improves performance for transpiling, type checking, and more, proponents say. Prior to the Deno 1.24 release, Deno internally converted TypeScript code to JavaScript using the TypeScript compiler when the 1–check flag was specified; otherwise, it used Read more…
In this article, you’ll learn about Node.js and Deno, the differences between CommonJS and ECMAScript modules, using TypeScript with Deno, and faster deployments with Deno Deploy. We’ll conclude with notes to help you decide between using Node.js or Deno for your next development project. What is Node.js? Node.js is a Read more…
Changes are in the offing for the Deno TypeScript/JavaScript runtime, with plans afoot to make it easier to import NPM packages and to enable most of them to work in Deno. The project’s developers also aim to make Deno the fastest JavaScript runtime. In a blog post on August 15, Read more…
#452 — September 1, 2022 Read on the Web Tinybench: A Tiny and Simple Benchmarking Library — No dependencies, but uses whatever precise timing capabilities are available (e.g. 1process.hrtime ). You can then benchmark whatever functions you want, specify how long or how many times to benchmark for, and get Read more…
