You are not alone! Most people confuse Java with JavaScript, no thanks to the identical “Java” name. Though this might seem like a harmless mistake, some techies find it extremely annoying when you don’t get your “Java” right. Though they share a common history that is linked to the reign of Netscape, they aren’t exactly two peas in a pod. Interested in knowing what makes these seemingly similar IT products poles apart? Of course, you are! So, let’s get down to business.
Java isn’t Javascript
Java is a class-based programming language developed by Sun Microsystems. It is an independent language that runs off Java Virtual Machine (JVM) — a software that allows Java programs to operate on any and all platforms.
Javascript on the other hand is an interpreted high-level programming language deployed by interactive web applications. While Java is a tough nut to crack, JavaScript is easy to learn and execute. It is also compatible with other languages and can be used across web applications.
While Java is an object-oriented programming language that is independent of other programming platforms (thanks to JVM), JavaScript is an object-oriented scripting language that is involved in the development of dynamic HTML pages. Notice the difference?
They Have Different Applications
While Java is used for server-side developments, JavaScript excels at developing client-side scripts for functions like interactivity and validation.
They Operate Differently
You should know that Java and JavaScript run on opposite sides of the spectrum. In other words, they don’t have the same modus operandi. Applications that are end products of either Java or JavaScript run differently (in no small measure). While Java develops applications that run seamlessly on browsers and virtual machines, JavaScript applications run on browsers only.
They Feature Separate Uses
Java has several uses including the development of Android, desktop, and banking and financial applications. Conversely, JavaScript is solely reserved for enhancing the creativity and interaction of web apps. It also aids the creation of animations in HTML.
Compiled Vs Interpreted
While Java is a compiling language, JavaScript is an interpreted scripting language. Both languages operate differently. Java is compiled into bytecode and operates on Java Virtual Machine while JavaScript is directly interpreted by a browser (in syntax) with pre-written code.
Benefits
Java and JavaScript have benefits that are unique to each. The advantages of using Java include:
- It is a platform-independent programming language that allows its applications to run on any platform with a JVM feature. Java can also be used to develop programs that run on desktops, embedded systems, and mobiles.
- It supports multithreading which means it can perform several tasks simultaneously.
- It offers a secure environment for the development of applications. It keeps software viruses at bay and prevents misuse of resources.
- It is a dynamic language; all its classes, methods, objects, and libraries are dynamically linked to Java. It also supports several functions that are written in other languages like C and C++.
The key advantages of using JavaScript include:
- It is a client-side scripting language which means the source code is executed on the client’s browser and not otherwise. Hence, a server-side browser isn’t needed to process the code.
- It provides several solid and robust frameworks that aid the development process. The framework is packed with ready-to-use codes that are easily debugged
- Users of JavaScript are treated to procedure-based features that add to the overall appeal of their websites.
- It provides concurrency, so users can perform multiple tasks at the same time. You can use a single thread to execute several tasks, thus saving time and effort.
Conclusion
Now you know the differences between Java and Javascript in full detail. So, if you are still asking yourself “Should I learn Java or JavaScript”? you know your answer. On the whole, Java provides security and robustness for your app, while JavaScript enhances its look and feel.
