Java vs. JavaScript: 7 Key Differences, Pros & Cons, Examples

Java vs. JavaScript are both the two most famous languages in the programming world. But most people confuse these with each other, and some make the mistake of thinking that Java is a short form of JavaScript; in truth, these two languages differ in many ways. The main difference between Java and JavaScript is that Java is a static language used for android apps and back-end development. While JavaScript is a dynamic language which is more into games and website development.

What Is Java?

What Is Java? If we look at Java meaning: it is a static language which has a rigid syntax around declaring variables. Java is a language used for android app and back-end development. It was developed in 1995 by Sun microsystems, but later on, it was taken over by Oracle. It is a vast language with manybooks, online articles, documentation and forums that you can learn easily. Java is basically a programming language. Therefore, this program is compiled as well as interpreted. Java is also very popular as it is used for many different tasks, including large-scale projects by enterprises, trade, financial and automotive industries. It is also used in the development, Hardware, scientific computing and the internet of things like smart refrigerators and Sonos speakers.

What Is JavaScript?

What Is JavaScript? If we look at JavaScript meaning: It is a dynamic language which is more interested in games and website development. JavaScript was developed earlier than Java in 1990 and was made by Netscape. It is a bit smaller than Java, but it also has a vast forum and online documentation, which are easy to learn. It is also an object-based scripting language, but in this, the objects are prototype-based. Which means it is not bound to any patterns. JavaScript is famous as “ The Language of the Web", dominating web development. It is used in development and web-based projects. But the abilities of JavaScript have been extended due to huge APIs and Libraries. It is a weaker language but easier if all the rules are being followed.

DefinitionJava is a static language which has a rigid syntax around declaring variables. It is a language used for android app and back-end development.If we look at JavaScript meaning: It is a dynamic language which is more interested in games and website development.
HistoryIt was developed in 1995 by Sun microsystems, but later on, it was taken over by Oracle.JavaScript was developed earlier than Java in 1990 and was made by Netscape.
CompilationJava is a programming language; therefore, this program is compiled and interpreted.On the other hand, JavaScript is a scripting language; therefore, it has plain code in text format and is interpreted.
Learning CurveIt is a vast language with many books, online articles, documentation and forums that you can learn easily.JavaScript is a bit smaller than Java, but it also has a vast forum and online documentation, which are easy to learn.
TypingIt is a strong type of language in which variables and other objects can be declared by using them.It is a weaker language but easier if all the rules are being followed.
Language & ObjectIt is an object-oriented programming language in which objects are class-based, which means you cannot create any program in Java without developing a class.It is also an object-based scripting language, but in this, the objects are prototype-based. Which means it is not bound to any patterns.
