For the past two decades, JavaScript has been the sole programming language natively supported in web browsers. During this time, the rise and fall of third-party plug-ins, such as Java and Flash’s ActionScript, have made it clear that web development would remain firmly in JavaScript’s domain. Other languages, like CoffeeScript, only served to compile into JavaScript rather than offering an alternative. This has kept web development constrained to a single language, limiting the performance and capabilities of web applications in some cases. However, the landscape is changing with the advent of WebAssembly, or Wasm. WebAssembly is a compact, fast binary…

The Eclipse Foundation is making a bold move to challenge Oracle Java with the introduction of an online marketplace designed to give developers access to Java binaries from a variety of sources. The new platform, called the Adoptium Marketplace, is being developed in collaboration with the Eclipse Foundation’s Adoptium Working Group. This marketplace will offer Java SE Technology Compatibility Kit (TCK) certified binaries, as well as Eclipse AQAvit (Adoptium Quality Assurance) Java binaries, all based on OpenJDK. While the TCK ensures compatibility with the Java platform, the AQAvit certification adds a layer of testing for performance and scalability, ensuring higher…

String manipulation is one of the most performance-sensitive aspects of application development. Since strings in C# are immutable, every operation that modifies a string, such as adding characters or extracting substrings, results in the creation of a new string object. Over time, this can lead to excessive memory allocations, which can have a negative impact on application performance, especially when working with large datasets or performing numerous string operations. Typically, when performing operations like string concatenation, new string instances are generated instead of reusing existing ones, which can increase memory usage and cause unnecessary allocations. A well-known solution to this…

Front-end architecture has become one of the most rapidly evolving areas in software development. As web applications grow more complex and user expectations continue to rise, developers are constantly seeking new ways to build dynamic, efficient, and responsive user interfaces. This drive for innovation is taking place at a remarkable pace, and the landscape is being shaped by a number of open-source JavaScript projects that are transforming how we think about front-end development. Some of the most notable projects leading the charge include SvelteKit, Solid, React, Qwik, and Astro. These frameworks and tools are giving developers a front-row seat to…

TypeScript 4.7 was officially released as a production version on May 24, bringing with it significant enhancements that improve both functionality and developer experience. This latest version of Microsoft’s strongly typed JavaScript includes full ECMAScript module (ESM) support for Node.js 16, a much-anticipated feature. Additionally, TypeScript 4.7 introduces a variety of coding enhancements aimed at refining the language’s capabilities and ensuring better compatibility with modern JavaScript features. A key highlight of TypeScript 4.7 is the addition of ESM support for Node.js 16, which was a last-minute inclusion in the release. Earlier in the beta phase, TypeScript 4.7 offered support for…

A long-discussed proposal to address persistent Java challenges, such as slow startup times, delayed peak performance, and large memory footprints, is finally advancing. Known as Project Leyden, this initiative seeks to mitigate these issues by introducing static images to the JDK and the Java platform. On May 20, Mark Reinhold, Oracle’s chief architect for the Java platform, announced in an OpenJDK post that it was time to move the project into its active development phase. Static images represent a significant shift in how Java applications are executed. A static image is essentially a standalone program derived from an application, designed…

Programming languages often balance two types of speed: the speed of development and the speed of execution. Python has historically prioritized development speed, allowing developers to write and iterate code quickly. While Python’s execution performance is typically sufficient for many tasks, there are instances where performance bottlenecks emerge. In such situations, it’s essential to identify the specific areas of the code causing delays and address them effectively. One of the golden rules in software development is, “Measure, don’t guess.” Assumptions about where the problem lies can often be misleading, leading developers to invest time optimizing parts of the code that…

The Jakarta Persistence API (JPA), formerly known as the Java Persistence API, is a specification focused on persistence—the ability of Java objects to outlive the application process that created them. While not all Java objects require persistence, key business objects in most applications typically do. JPA allows developers to define which objects should be persisted and outlines how this persistence is managed within Java applications, providing a standardized approach for handling data that needs to be stored and retrieved across application lifecycles. JPA itself is not a framework or tool; it is a specification that defines a set of concepts…

JavaScript and Python continue to dominate the programming landscape, but Rust is making significant strides in developer adoption, according to the latest global survey. The findings come from the 22nd edition of the “State of the Developer Nation” report by analyst firm SlashData. This survey, conducted between December 2021 and February 2022, gathered responses from over 20,000 developers across 166 countries. The results highlight JavaScript’s enduring popularity and Python’s rapid growth while spotlighting Rust’s impressive rise as a favored language among developers. JavaScript maintained its position as the most widely used programming language for the tenth consecutive survey, with nearly…

Multithreaded programming in Java may soon become significantly more accessible, thanks to a new proposal incubating within the OpenJDK community. This plan, called structured concurrency, introduces a novel library designed to treat multiple tasks running on different threads as a single unit of work. By simplifying error handling and task cancellation, the proposed library aims to improve the reliability and observability of concurrent Java applications. Although the proposal is still in its exploratory stages and not tied to any specific Java version, it holds promise for transforming how developers approach multithreaded code. Structured concurrency is centered on the principle of…
