Many people assume that since JavaScript has the word “Java” in its name, the two are somehow related. While many programmers complain about this similarity and many even feel that this naming confusion is just part of a marketing ploy, although the history of these two popular programming languages for a very brief moment during the early days Netscape met.
However, the evolution of the two programming languages took a completely different path from that point.
Anyway, if you’re reading this article, you’re probably interested in a brief and useful explanation of these two popular languages and want to know which one is better for learning, so let’s compare the two.

Javascript or Java?
If we go back about 5 years ago, there was a simple comparison, Java is a general-purpose programming language, and javascript is used in web applications to create animations and make them interactive. Now that JS has gotten bigger and bigger, comparing the two has gotten a lot more complicated.
First of all, take a look at some interesting facts and statistics about Java and JavaScript:
- Java’s original name was “Oak” and was changed to “Java” by Sun’s marketing department when they discovered that the name was already registered to some computer company.
- The Java programming language was created randomly. Around 1992, James Gosling was working at Sun Labs. He and his team were building a setup box, and this work started with the introduction of C++ language, The result of all their work led to a new programming language called Oak, or today’s Java.
- Java is the second most popular programming language and is very popular among web developers.
- The Java programming language is free from the concept of Pointer because adding pointers to the J programming language compromises its security and integrity and makes this programming language more complicated.
- In Java, the actual meaning of the keyword Final is not final, and it has different meanings in Java. It can be the Final method, Final class, Final variable, or Final string.
- Today, 95% of companies use Java as their primary programming language. Which is much more than the statistics of C and other programming languages.
- Annually, Java is downloaded about a billion times. And daily, Java is run more than 1 billion times because Google’s Android operating system uses Java APIs.
An overview of the history of Java and JavaScript
Java Script
In the early days of the Internet, around 1990, Internet Explorer and Netscape Navigator were two popular web browsers used by the general public. In just 10 days, a developer named Brendan Eich at Netscape. He was able to create a programming language so that the computer could receive user input data and interact with the user with the help of those inputs. He called this language “LiveScript”.
This means that the browser was interpreting the user’s commands. It was not necessary to compile the code and it was not necessary to have plugins.
Another programming language, called Java, became popular around the same time since Java required a separate plugin to function. Netscape took advantage of this opportunity and named its language “JavaScript”. The use of JavaScript was inevitable in the early days of the Internet.
Java programming language
Java is a programming language invented by James Gosling and developed by Sun Microsystems. Its development took about 10 days.
And then it stopped for nearly four years.
In 1991, a group of Sun Microsystems engineers called the “Green Team” worked day and night to build Java. It was first released in 1995 and since then many new versions have been launched.
The Internet today is completely saturated with Java-based programming, and today we have Java to thank for the many programs that make our daily lives easier with the help of Java. Currently, Java belongs to the Oracle computer company.
Now let’s see some differences and similarities between these two languages from the perspective of web application development:
Major similarities between Java and JavaScript
While the two languages are different, there are also many similarities, which are worth thinking about, especially if you are looking to develop web applications when comparing Java to JavaScript. Object Oriented Programming (OOP)
Both languages require the developer to encode the objects and relationships between them in each. Extensions allow both languages to access new features such as inheritance, encapsulation, and polymorphism.
- Front-end development
Both languages can be used in front-end aspects. JavaScript can be used directly in HTML and implemented as a framework or library. Java can be used as an applet (small program) in this Java field.
- Back-end development
Both languages can be used on the server side. Java has long been used to power powerful back-end technologies such as Apache, JBoss, and WebSphere.
Node.js has also become a backend for JavaScript servers.
The difference between Java and JavaScript
- Java is an OOP (Object Oriented Programming) language that was introduced in 1995. Java was developed at Sun Microsystems, which was later acquired by Oracle.
- Programs or applications developed in Java programming language will run in JVM (Java Virtual Machine) using which we can run the same program on different operating systems and platforms or devices.
- JavaScript is an OOP language (object-oriented scripting language) that you can use to create dynamic HTML pages and create interactive effects on a web page. JS was initially available in the browser until Google Chrome introduced its node engine as Released “node.js”.
- Both JavaScript and Java languages are marked up, written, and executed differently, and each has important differences in its capabilities.
- Java is used in many places, including credit card programming, Android applications, and creating desktop applications and investment-economic applications.
- In comparison, JavaScript was first used to make web application pages more interactive. It can be used as an alternative to Flash, although most web developers and programmers will tell you that JavaScript is more popular and has more functionality than Flash.
- JavaScript is used to do things like create animations in HTML.
In short, when it comes to how to use any programming language, Java is typically used for all server-side development, while creating user-side scripts for things like JS validation and creating JavaScript interactions. is used
Some other important differences are:
- JavaScript code is all text and does not need to be compiled, and Java code must be compiled.
- Each language needs different plugins.
- JS code runs only in a browser, while Java creates web applications that run in a browser or a virtual machine.
- Java is an object-oriented programming language (OOP), and JS is specifically a peripheral object-oriented programming language.
- A new programming student learns that JavaScript and Java are meaningful programming languages to add to their coding portfolio. Many programmers say that quickly learning these two programming languages is a very wise move for a novice programmer.
- Undoubtedly, learning JavaScript and Java at the same time creates more profitable employment opportunities for a coder.
Should I use JavaScript or Java in my next project?
Today, software development companies in India and other parts of the world use both these programming languages to create secure, scalable, and feature-packed applications according to business requirements
As with all programming languages, the choice depends on what you are willing to do and what you need to do to create your idea. JS is still more of a web technology and is evolving every day, while Java is a general-purpose programming language that can create anything.
Hourly rate of salary for Java and JavaScript developers
When you hire dedicated developers, their hourly rate depends on various factors such as the complexity of the project, the level and scope of the work, the complexity of the workspace, the geographical location, and of course the type of programming language you work with.
In this respect, JavaScript and Java are quite similar to each other, and hourly rates for both languages are between $61 and $80 globally.
However, if you need to hire software developers for Java or JavaScript, relying on this global average rate is not enough. Because a young software engineer in the United States may cost more than a senior programmer in Eastern Europe. But since people have different levels of expertise. We strongly recommend that you consider a dedicated development team with different people for your project.
It is better to take a closer look at this issue:
United States of America
The US is the most expensive country in terms of software development services. For example, the average annual salary of a Java developer in the US is $104,663, on the other hand, JavaScript developers earn approximately $105,744 per year. Hence, the hourly rate ranges from $50 to $150. The quality of service is usually at a higher level.
Europe
When you hire Java programmers or JavaScript developers in Europe, their hourly rates are different in Western and Eastern Europe.
Although the income of developers in Western European countries such as Germany is high, the situation is completely different in Eastern Europe. For example, the rates paid to Ukrainian developers (both JavaScript and Java) are between $25 and $50 per hour.
As you can see, this figure is slightly lower than the average rates worldwide. If you decide to hire a web developer for Java or JavaScript from Ukraine, you will not pay much. Although Eastern European programmers have excellent expertise and work approach.
Asia
Programming in Asia is considered the “cheapest”, which means that developers have the lowest rates for their work. For example, a JavaScript or Java developer from Pakistan may cost around $8-10 per hour. However, this low price usually comes with low quality. We advise you to be cautious if you decide to look for a coding team in Asia. There is a risk that you end up with a half-finished project and need to start all over again.
