Today, this critical web technology is a key component of most popular web browsers. Once AOL acquired Netscape and the Mozilla Foundation gained access to Netscape Navigator’s source code, JavaScript grew in popularity. He created Mocha, the predecessor to JavaScript. It was in 1995 that Brendan Eich, a Netscape team member, took on the challenge of building such a language within ten days. To win this ‘browser war’, Netscape was looking for a lightweight scripting language to make programming easier and remove the need for in-depth programming knowledge among employees. Two major companies, Microsoft and Netscape, wanted to push out Internet Explorer and Netscape Navigator, intending to dominate the web browser market. As the world increasingly gained internet access in the 1990s, technology pioneers raced to build a robust, efficient internet browser. Like Java, JavaScript’s origins lie in the early days of the world wide web. Inside web browsers and other host environments, JavaScript offers connectivity among objects, enabling users to exercise programmatic control over them. A few everyday use cases for JavaScript include creating clickable buttons, complex animations, and pop-up menus.Īdvanced server-side JavaScript versions like Node.js enable users to boost website functionality with features such as real-time collaboration. JavaScript is an object-oriented scripting language that offers cross-platform functionality and is primarily used for creating interactive web pages. See More: What Are Microservices? Definition, Examples, Architecture, and Best Practices for 2022 What Is JavaScript? While it can be (and is) used for smaller applications, it might be a little heavyweight for quick DevOps scripts. It is better suited for creating large enterprise software solutions. Java’s ubiquitousness is apparent in that even tech giants such as Google and Amazon use it. ![]() While the Java code running on an Android smartphone may appear to be different from the code for a web application, it is the same source code. Instead, the source code is compiled explicitly for the Android runtime. One everyday use of Java is in Android-powered smartphones however, JVM is not used here. Developers can use many Java implementations for free, including OpenJDK, the open-source counterpart of Oracle’s proprietary Java Development Kit (JDK). The Java language is open-source, as are many purpose-built Java tools, frameworks, and libraries. The fact that Java is an object-oriented language also means that its foundational concepts are transferable to other programming languages. As such, learning Java makes learning more accessible than other widely used languages such as JavaScript, C#, and C++. It is also perhaps the most used language among programmers, making it easier for newbies to find mentors.Īdditionally, Java syntax is derived from C, like numerous other languages. It has been in mainstream use for over two decades and is well-established, with numerous excellent resources for learning it. Today, Java is an excellent first language to learn for people trying their hand at programming. These small programs could be executed inside web browsers, giving Java a unique functionality that led to its popularity for writing many web applications. Instead, it was the rise of the world wide web another early Java feature was its usage for writing applets. ![]() However, this was not the original reason for Java’s popularity. One of the key features of Java is ‘write once, run anywhere’, enabling programmers to write code that one can compile for execution on any device. Interestingly, Java was initially envisioned as a programming language that would run on consumer appliances, a concept we now know as the internet of things (IoT). Subsequently, the company was acquired by Oracle Corporation, making Oracle the official owner of the Java SE platform. Sun Microsystems was the creator of Java, releasing it in 1995. ![]() However, that is no longer the case new languages such as Groovy, Scala, JRuby (an implementation of Ruby), and Jython (an implementation of Python) are written for execution on the Java platform. Initially, both terms were interchangeable because Java was the only language that ran on JVM. It also serves as a platform, enabling Java code to be executed on any computer powered by a Java Virtual Machine (JVM). Java is an all-purpose, object-oriented programming language. While Java is an object-oriented, class-based, all-purpose programming language, JavaScript is an object-oriented, cross-platform scripting language for creating interactive web content.
