Difference between Java and JavaScript

In here we are going to talk about basic difference between the Java and Java Script.

Let’s get started!

introduction to java:

java is a OOP language similar to C++ found by Sun Microsystem in 1991. Java is a most reliable, secure and fast language among programming languages. And also Java use for Banking, Information Technology, Financial Services, Stock market and various kind of industries. Because of Java is master of all programming languages.

Now let’s move on to basic features of JAVA:

  1. Use OOP concept :- Java uses object-oriented concepts like object, class, inheritance, encapsulation, polymorphism, and abstraction.
  2. Easy to learn :- this language is easy to learn and understand because it’s based on C++.some syntax are same to C++.
  3. Secured :- In java , the code you wrote can easily convert into byte code after compilation. Byte codes are unable to read or understand to other parties. So it’s helpful for us to when making secured applications.
  4. Strong memory :- Java built using reliable and strong memories so it can eliminate errors in the code in any level in compilation.
  5. Platform independent :- Java code can run on multiple platforms directly. we not need to compile every time.

Now learn about JavaScript :

JavaScript was invented by Brendan Eich in September 1995. JavaScript is a high-Level language that join JIT compiler and works on curly-bracket syntax with ease

JavaScript is a text-based programming language used on client and server side that allows you to make web pages interactive. Where HTML and CSS are language that give structure and style to web pages. Then JavaScript gives web pages interactive elements that engage a user. And also APIs, XML and the most recent Node JS are some of the places where JavaScript is used.

Now let’s move on to basic features of JavaScript:

  1. Speed :- Client-side JavaScript is very fast because it can be run immediately within the client-side browser. Unless outside resources are required, JavaScript is unhindered by network calls to a backend server.
  2. Simplicity :- JavaScript is relatively simple to learn and implement.
  3. Popularity :- JavaScript is used everywhere on the web.
  4. Interoperability :- JavaScript plays nicely with other languages and can be used in a huge variety of applications.
  5. Server Load :- Being client-side reduces the demand on the website server.


Java and JavaScript, both languages need expertise and an extensive approach to learn and execute in the respective platform. So, Programmers should study both of them to be successful in your career.
