JavaScript vs. Core Java: Which is Better?

It's difficult to say which is "better" between JavaScript and Core Java, as they are two different programming languages with different use cases and strengths.


JavaScript is a popular and widely-used language for web development. It is used to create interactive web pages and is supported by all modern web browsers. JavaScript is a dynamically-typed language, which means that you don't need to specify the data type of a variable when you declare it. This can make JavaScript code easier to write and maintain, but it can also make it harder to catch type-related errors.

Core Java

Core Java, on the other hand, is a statically-typed language that is commonly used for building standalone applications and Android mobile apps. It is a more powerful and feature-rich language than JavaScript, but it can also be more complex and require more code to accomplish the same tasks.

Ultimately, which language is better for you will depend on the specific needs of your project. If you are building a web application, JavaScript is likely the better choice. If you are building a standalone application or an Android app, Core Java might be a better choice.

Is JavaScript Better than Core Java?

We need to compare the factors that make JavaScript lead from Java to know if JavaScript is better than core Java. As we know, Java and Javascript are object-oriented. Java is a programming language, and Javascript is a scripting language.

Since Javascript works in front-end and back-end technologies, we call it a full-stack programming language. Java is server-based and uses Javascript for several purposes. Javascript is becoming incredibly essential for programmers presently. Let us compare Javascript and core Java to understand the benefits of Javascript.

JavaScript vs. Core Java

The following table highlights the major differences between JavaScript and Core Java −

Factors of Comparision JavaScript Core Java


JavaScript is faster than Java

Java is slower than JavaScript


JavaScript runs on the browser directly

Java needs Java Virtual Machine to run


JavaScript is easy to learn than Java

Java is not very easy to learn


JavaScript has more market than Java

Java market is less than Javascript


JavaScript memory requirement is comparatively less than Java

Java requires large memory for multi-thread feature

Data type

Dynamic data typing makes web development easy in Javascript.Javascript is a weakly typed script.

Need not declare variable type in Javascript.

Static data typing makes web development difficult in Java.

Java is a strongly typed programming language.

Must declare variable type in Java.


Javascript is dynamic

Java is static

Developer Salary

Javascript developer salary is pretty good than the Java developer salary in the United States of America.

Java developer salary is not up to expectation

Hardware cost

JavaScript hardware cost is less than Java

Java hardware cost is more than Javascript

Support for pointers

Javascript support pointers

Java does not support pointers


Javascript is lightweight

Java is not lightweight


Javascript allows passing a function as an argument to another function

Java does not allow a function as an argument to another function

Development platform

Javascript needs only a text editor

Java requires a development kit

Popularity in UI development

Javascript is very popular in UI development

Java is not popular in UI development

Switch structure

The javascript switch structure accepts all values

Java switch format takes only constants

Garbage collection

Javascript removes garbage automatically

Java has no user control over garbage collection

Software Integration

JavaScript Integrates software well

Software integration is poor in Java

Maintaining code

Javascript maintains code well

Java does not preserve code well

Programming type

Javascript supports both functional programming and object-oriented programming.

Java supports only object-based programming.


We have analyzed the factors that make JavaScript more outstanding than Java. The fundamental factor is simplicity. Other factors are popularity in UI development, developer salary, speed, and demand in the IT field.
