Diffence between JavaScript and java:-
JavScript and Java are two completely different programming language in both
concept and design.
JavaScript:-
- JavaScript is invented by "Brendan Eich".
- 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 at the first time,but later on ,it has
been adopted by 'ECMA' (a standard browser) in 1997.
- 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 prototype based language ,not
class based .
- 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 decimal symbol.
eg. var pi=3.14 // A number with decimal
var x=36 // A number without decimal
In case of 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:-
- Java is invented by "Sun Microsytsems" and designed by 'James Gosling'.
- It is more complex OOP based programming
language and come in same catagory as 'C' language.Its first name is "Oak".
- Java is a 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 these objects.Java is class based language.
- 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
