Difference between JavaScript and Java

In this blog you will look an abridged description at JavaScript which is completely differ from Java.

Difference between JavaScript and java

javascript and Java are two completely different programming language in both concept and design.

JavaScript:-

1. JavaScript is invented by "Brendan Eich".
2. It is a scripting programming language and its official name is 'ECMA-262'. It viewed on the 'Netscape' browser (i.e. no longer used browser) in 1995 for the first time, but later on, it has been adopted by 'ECMA' (a standard browser) in 1997.
3. JavaScript is an Object-Oriented Language, but it doesn't still use classes and create objects from these classes, unlike other languages. Thus it is a prototype-based language, not class-based.
4. JavaScript isn't a typed language. Due to this, it can be defined only 'one type of Number' that can be written either with or without a decimal symbol.
   eg. var pi=3.14 // A number with a decimal
   var x=36 // A number without decimal
   In case of an extra-large or extra small number you can be written these numbers using exponential(scientific symbol) as given in example:-
   eg. var x=136e6 //means 136000000
   var y=136e-6 //means 0.000136

Java:-

1. Java is invented by "Sun Microsystems" and designed by 'James Gosling'.
   
2. It is a more complex OOP based programming language and come in the same category as 'C' language. Its first name is "Oak".
3. Java is such Object-Oriented Language in which we can define a number of classes and create a number of objects from these classes, as well as instances of this objects.Java, is class-based language.
4. Unlike JavaScript, it can define 'Different types of Numbers' like Integer, Short, Long and Floating-Point number etc.
   eg Int var x;  //an integer variable
