Java vs JavaScript: Difference You Should Know

Although the word “Java” appears in both Java and Javascript, they are completely different from one another despite how similar they may seem to the human ear. Although creating online and mobile applications is one of the many things that Java and Javascript are used for, there are some very significant distinctions between the two languages. We will examine the differences between Java and Javascript in this post, as well as any similarities.

In this article, we have explained the differentiation between Java and JavaScript explained with detail.

Java is a general-purpose, class-based, object-oriented programming language intended to have as few implementation dependencies as possible. James Gosling created it at Sun Microsystems first, and it was made public in 1995. Web development and mobile application development are two of Java’s most popular applications, however, it has many other uses as well. In addition to that, it is also utilized in desktop, embedded, and scientific applications. In addition to PCs, smartphones, printers, ATMs, home security systems, and other devices, Java is supported by 3 billion devices globally.

JavaScript, abbreviated as JS, is a multi-paradigm, high-level, just-in-time compiled programming language that adheres to the ECMAScript specification. Curly bracket syntax, dynamic typing, proto-type-based object orientation, and first-class functions are all part of it. JS contributes to the core technologies of the World Wide Web, and many websites use it for client-side page behavior. As a language with multiple paradigms. To create interactive web pages, JS supports and enables event-driven, functional, and imperative programming styles. It provides APIs for manipulating text, regular expressions, dates, data structures, and the Document Object Model (DOM).

Let us now look at the differences between Java and JavaScript.

The main distinction between the two languages is their programming paradigm, or how a programming language approaches a problem to solve it. Java is an object-oriented programming (OOP) language. However, JS is a multi-paradigm language that can be used as an OOP, procedural, or scripting language.

Type checking validates a variable’s “type.” JS is a dynamical type language, which means that the type of variable is unknown until the program is compiled. On the contrary, because Java is a statically typed language, each variable must be associated with a type at the time of declaration.

Inheritance is the concept that allows one entity to inherit or derive the properties of another entity. A class in Java can derive the properties of another class. It also allows for multiple inheritances, which means that a class can derive properties from multiple classes.

JS is based on the prototype concept and does not support multiple inheritances.

The programming language can define two or more functions with the same name for performing different tasks using function overloading. The functions, on the other hand, differ based on their arguments. Java allows for function overloading, whereas JS does not.

Multithreading reduces execution time by running multiple parts of a program concurrently, utilizing CPU power. Because the interpreter inside the browser is single-threaded, Java supports multithreading, whereas JS does not.
