In the modern world of browsers, such as Google Chrome, Mozilla Firefox, Microsoft Edge, and Safari, JavaScript remains the dominant and widely supported language used for programming and interacting with web pages. This raises an important question: why haven’t major companies agreed on integrating other programming languages alongside JavaScript? Is it merely competition, or are there deeper scientific and logical reasons behind this? Let’s explore this issue from various perspectives:
JavaScript has become an integral part of web standards set by global organizations like W3C (responsible for web standards) and ECMA International (responsible for ECMAScript standards, which include JavaScript). These organizations focus on ensuring compatibility across all browsers to provide a unified user experience, regardless of the browser being used.
Developing a new programming language requires not only defining the specifications of the language but also ensuring widespread support across all browsers and coordinating with the responsible bodies. This would take considerable time and require fundamental changes to the current web ecosystem.
One of the primary reasons for JavaScript’s dominance in browsers is its ability to operate within a restricted environment known as a "sandbox," which ensures security. Browsers allocate a controlled execution environment to maintain user security and mitigate risks from malicious programs or cyberattacks. JavaScript is already well-integrated into this environment, making it easier to manage and monitor performance.
Integrating another programming language into browsers could increase the system's complexity and expose it to new security risks. These languages may not have the same level of security or control that JavaScript offers, making browser companies hesitant to adopt them.
Since the 1990s, JavaScript has been the dominant language of the web. An enormous ecosystem of tools and technologies has been developed around it, including libraries such as jQuery, React, Angular, Vue.js, and engines like V8 (used in Chrome). These represent a massive investment in time and resources, leading companies and developers to adopt JavaScript more widely and deepen their commitment to it.
Any drastic change, such as integrating a new programming language, would require rebuilding these tools and libraries, which is impractical for the web industry that relies on quick performance and ongoing compatibility.
Although JavaScript has received some criticism regarding performance, improvements in the language over the years, especially with fast engines like V8, have significantly enhanced its performance. Many companies now rely on technologies like WebAssembly to introduce high-performance programming through languages like C++ or Rust, without needing to abandon JavaScript. WebAssembly allows code to run at speeds similar to native code, providing a suitable alternative to integrating other languages.
Competition between browser development companies is part of the issue. Each company has its own vision for the browser and the technologies they want to support. Integrating a new programming language would require extensive coordination among these companies, but competition sometimes leads to complexities that make agreeing on a single language challenging.
JavaScript is designed to handle memory management efficiently and safely through a mechanism known as "Garbage Collection," which allows developers to work without worrying about resource management directly. Most other programming languages require a higher level of manual control over memory management, which increases complexity for developers, especially in an open environment like the web.
The primary reason behind the lack of integration of other programming languages alongside JavaScript in modern browsers is not solely the competition among major companies, but also technical factors such as security, compatibility, and the vast investment in the current JavaScript ecosystem. This does not mean that other programming languages are incapable of offering better performance, but integrating them would require fundamental changes to the architecture of browsers and how web applications are managed.
