ADMEC Multimedia > Web Design > JavaScript vs Java – Major Differences

Programming world is getting bigger day by day. Some people get confused when they heard of some similar names of programming languages. One of the instances is Java and JavaScript. Both of these languages are way different from each other but many who listen about them for the first time assume both of them from the same family. Though now a days there are many institutes which offers promising JavaScript course in Delhi as well as Core Java Course.

I have dedicated this whole blog to the differences between these two, just to make everyone understand who has even a little bit doubt about their difference.

Let’s Begin!!!

What is JavaScript?

JavaScript which can be abbreviated as JS is a web designing language. It is open source, high level as well as interpretable language which was obeys all ECMAScript Specification.  It is a language which is used along HTML and CSS. Its role is to provide interactivity among different webpages. This along with its frameworks such as Angular, React, Vue.js, Node.js etc is giving an edge to web development world. With these there is a noticeable shift, that earlier it was just used as a client-side language and now it is also used as server-side language.

What is Java?

It is a platform builds a program which is platform independent. It is free. Along with this it is so vast that you can modify its use according to the job skills that are required by you. It can be used to create complete applications to small applets that are used in webpage. It is the best language to go for if you already have sound knowledge of c and C++.

This was just a brief about both the languages.

Now, let’s know…

The Difference Between JavaScript and Java:

S. No.JavaScript (JS)Java
1JS is loosely typed. That means, it is written in a more relaxed manner than JavaIt is strongly types language. That means, it is written
