What s the difference between JavaScript and Java

Question

User · Answer

Like everybody s saying  they re pretty much entirely different   However  if you need a scripting language for your Java application  Javascript is actually a really good choice   There are ways to get Javascript running in the JVM and you can access and manipulate Java classes pretty seamlessly once you do

User · Answer

Practically every PC in the world sells with at least one JavaScript interpreter installed on it   Most  but not  practically all   PCs have a Java VM installed

Everything   JavaScript was named this way by Netscape to confuse the unwary into thinking it had something to do with Java  the buzzword of the day  and it succeeded   The two languages are entirely distinct

They are independent languages with unrelated lineages  Brendan Eich created Javascript originally at Netscape  It was initially called Mocha  The choice of Javascript as a name was a nod  if you will  to the then ascendant Java programming language  developed at Sun by Patrick Naughton  James Gosling  et  al

JavaScript is an object-oriented scripting language that allows you to create dynamic HTML pages  allowing you to process input data and maintain data  usually within the browser   Java is a programming language  core set of libraries  and virtual machine platform that allows you to create compiled programs that run on nearly every platform  without distribution of source code in its raw form or recompilation   While the two have similar names  they are really two completely different programming languages models platforms  and are used to solve completely different sets of problems   Also  this is directly from the Wikipedia Javascript article      A common misconception is that JavaScript is similar or closely related to Java  this is not so  Both have a C-like syntax  are object-oriented  are typically sandboxed and are widely used in client-side Web applications  but the similarities end there  Java has static typing  JavaScript s typing is dynamic  meaning a variable can hold an object of any type and cannot be restricted   Java is loaded from compiled bytecode  JavaScript is loaded as human-readable code  C is their last common ancestor language

In addittion to being entirely different languages  in my experience    Java looks nice at first  later it gets annoying  JavaScript looks awful and hopeless at first  then gradually you really start to like it     But this may just have more to do with my preference of functional programming over OO programming

A Re-Introduction to Javascript by the Mozilla team  they make Firefox  should explain it

User · Answer

Java and Javascript are similar like Car and Carpet are similar

User · Answer

They have nothing to do with each other   Java is statically typed  compiles  runs on its own VM   Javascript is dynamically typed  interpreted  and runs in a browser  It also has first-class functions and anonymous functions  which Java does not  It has direct access to web-page elements  which makes it useful for doing client-side processing   They are also somewhat similar in syntax  but that s about it

Here are some differences between the two languages    Java is a statically typed language  JavaScript is dynamic  Java is class-based  JavaScript is prototype-based  Java constructors are special functions that can only be called at object creation  JavaScript  constructors  are just standard functions  Java requires all non-block statements to end with a semicolon  JavaScript inserts semicolons at the ends of certain lines  Java uses block-based scoping  JavaScript uses function-based scoping  Java has an implicit this scope for non-static methods  and implicit class scope  JavaScript has implicit global scope    Here are some features that I think are particular strengths of JavaScript    JavaScript supports closures  Java can simulate sort-of  closures  using anonymous classes   Real closures may be supported in a future version of Java   All JavaScript functions are variadic  Java functions are only variadic if explicitly marked  JavaScript prototypes can be redefined at runtime  and has immediate effect for all referring objects  Java classes cannot be redefined in a way that affects any existing object instances  JavaScript allows methods in an object to be redefined independently of its prototype  think eigenclasses in Ruby  but on steroids   methods in a Java object are tied to its class  and cannot be redefined at runtime

Take a look at the Wikipedia link      JavaScript  despite the name  is essentially unrelated to the Java programming language  although both have the common C syntax  and JavaScript copies many Java names and naming conventions  The language was originally named  LiveScript  but was renamed in a co-marketing deal between Netscape and Sun  in exchange for Netscape bundling Sun s Java runtime with their then-dominant browser  The key design principles within JavaScript are inherited from the Self and Scheme programming languages

Don t be confused with name   Java was created at Sun Microsystems  now Oracle   But  JavaScript was created at Netscape  now Mozilla  in the early days of the Web  and technically     Java-Script    is a trademark licensed from Sun Microsystems used to describe Netscape   s implementation of the language  Netscape submitted the language for standardization to ECMA  European Computer Manufacturer   s Association  and because of trademark issues  the standardized version of the language was stuck with the awkward name    ECMAScript     For the same trademark reasons  Microsoft   s version of the language is formally known as    JScript     In practice  just about everyone calls the language JavaScript  The real name is    ECMAScript        Both are fully different languages
