Java was created in the 1990s by James Gosling and was designed to run on multiple devices through Java virtual machines. JavaScript was created in 1995 by Brendan Eich for web browsers and was renamed from Mocha to associate it with the popular Java. While Java focuses on write once run anywhere, JavaScript aimed to make the web more interactive. The two languages have some similarities like supporting object oriented programming and front-end and server-side development, but also have differences like Java having a simpler learning curve initially and JavaScript frameworks adding complexity.

JavaVs JavaScript
Comparing Java and JavaScript is like
comparing apples and oranges. Both are
different languages except few similarities. In
this article, we will try to cover all the
differences between both the languages.
JavaVs JavaScript – History :
Java first came into the picture in the 1990s, and James Gosling and his team are
credited for writing the code of Java. It was first called Oak, and it was written to run in
multiple devices like remote controls, television sets, etc. Initial development was
done on the campus of Sun Microsystem. After Oracle’s acquisition of sun
microsystem, Java is maintained by Oracle. Over a period of time, Several java
runtimes have been developed by different organizations.

Brendan Eich created JavaScript in 1995 for Netscape Navigator. In
earlier days it was called Mocha and, but the Netscape team changed its
name to JavaScript to show the Netscape navigator’s Java
programming language support. It was purely a marketing tactic to
make the name sync with the popular programming language Java. It
was designed for informal programmers and was considered as a “glue
language” for component interaction over the web. ECMA is the
organization which is responsible for the development and
maintenance of javascript. Over the period of time different
frameworks and scripting languages have evolved using javascript.

JavaVs JavaScript – Philosophy :
The main philosophy behind the designing of Java
programming language was “write once and run anywhere” which
means the language need not depend on any platform instead
would run on Java virtual machine.
The main idea behind the development of JavaScript was to give
an edge to the informal programmer and to increase the web
components interaction so that internet is more interactive. It was
the freedom void of any constraint in writing the code that made
JavaScript quite popular.
Below are some of the significant differences you can find between
Java and JavaScript

Java learning curve is simple and easy, but the latest version of
Java from JDK 1.8 onwards with the introduction of Nashorn
scripting engine it has enabled javascript type scripting and
support for the same thus new learning curve would also require
to follow the lines of the javascript learning curve.
The JavaScript learning curve is believed to be quite steep and
each framework and library have different complexities when it
comes to the learning curve.

Let us now discuss some of the similarities between Java and
javascript
Both Java and Javascript support front-end development. Java has
jsps, JavaFX to help in front-end development. Javascript
community has a large number of frameworks and libraries like
jquery, react, etc.. which provides a lot of options to develop front-
end.

Both Java and javascript support object-oriented programming
concepts. Though Java follows a class-based hierarchy, javascript
follows a prototypal hierarchy, which means each object can
inherit properties of other objects.
Both Java and javascript support server-side programming.
Although Java is more favored for server-side programming as
compared to JavaScript, later also has got good options for server-
side programming and one of the popular platforms is node.js,
which is supported server-side development work using
Javascript.

java Vs JavaScript Conclusion :
Java and JavaScript have been in existence for a long time. Java’s
popularity is still quite immense though in some areas it has given
way to JavaScript. Major banking and financial transactions involve
Java programming, and it can’t be replaced by JavaScript so easily.
On the other hand, JavaScript gained popularity in the past few
years and has tried to enter the cloud programming, server-side
programming space with its node.js platform. Only time will tell
whether JavaScript will be an ideal candidate to replace Java.
