Java vs JavaScript

Java:


Developed by Sun Microsystems, Java is a class-based programming language. It is a standalone language that is executed in JVM( Java Virtual Machine) that allows Java programs to run on any platform.
Java with its secured environment and great compatibility has emerged as one of the best programming languages. The language is favored by enterprises too. More than 90 percent of Fortune 500 companies use Java for building applications and back end systems. This is why large enterprises these days hire Java developer for creating custom-tailored web applications.


JavaScript:


JavaScript is an interpreted high-level programming language that helps to make web applications more interactive and responsive. According to Stack Overflow’s 2018 Developer Survey, JavaScript is the most popular language among developers for the sixth year in a row.
Unlike Java, JavaScript is simple to learn. That’s why it is used everywhere for web development. JavaScript can easily be used with other languages within different types of web applications.
What’s similar between Java and JavaScript?
Before you proceed further to read more on Java vs JavaScript, let’s have a quick look at the major similarities shared by the two

Java vs JavaScript: What’s the Difference?


Java is an Object-Oriented Programming language that is platform-independent because it gets executed in the Java Virtual Machine (JVM). On the other hand, JavaScript is an object-oriented scripting language that helps to create dynamic HTML pages. Java vs JavaScript has become a hot topic of discussion these days.
Purpose
While Java is used for all server-side development, JavaScript is primarily used for writing client-side scripts for tasks such as JS validation and interactivity.
Applications run differently
When we talk about Java vs JavaScript, then it’s important to know how these applications run. The applications created either using Java or JavaScript run entirely differently. Java develops applications that can run in a browser or virtual machine whereas applications made using JavaScript can run on a browser only.
Usability
Java applications are used in a number of places which include, Android applications, creation of the desktop applications, development of banking and financial apps. However, the use of JavaScript is limited to making web apps more interactive and creative. It also renders help in creating animations in HTML.
Compiled vs Interpreted
Java is a compiling language whereas JavaScript is an interpreted scripting language. These two languages run differently. While Java code is compiled into bytecode and run on Java Virtual Machine, whereas JavaScript is interpreted directly by a browser in the syntax in which the code has been written.
Key benefits of using Java
Java is a general-purpose programming language that is object-based and class-based. It is a high-level language that supports multi-threading. Java continues to deliver its prominent services in the field of software development. Major advantages that Java offers to the users include,
Platform-independent
One of the most important features of Java is that it is a platform-independent language. All Java programs can be compiled independently of the platform. The programs are compiled in the bytecode thus allowing the programs to run on any platform that has a JVM installed in it. You can use Java to create programs that can run across desktops, mobiles, and embedded systems.
Multi-Threading
Java is an object-oriented programming language that can perform several tasks at the same time. As it supports multi threading so Java has the capability to perform several tasks simultaneously.
Robust and Secure
Java offers a secured environment for the development of applications. It prevents the attack of viruses and keeps a check on the misuse of resources. It implements exception handling to remove errors and to reduce the risk of crashing.
Dynamic and Extensible
Java is a dynamic language. All the classes, objects, methods and libraries in Java are dynamically linked in Java. This extensible language supports various functions that are written in other languages such as C and C++.
