Write down difference between JavaScript and (Java,C,Ruby,PHP,cSharp and Python)?
Below are the most available difference between JavaScript and Java,C,Ruby,PHP,C# and Python:-
(A)JavaScript vs Java
(1)JavaScript is dynamically and Java is statically types.
(2)JavaScript is not strongly typed but Java is strongly typed.
(3)Java have features that it is programming explicit control over threading like C#. And JavaScript hides much of this with its call-and-response function structure.
(4)In some of Java version like Java 8 have mechanism to embed JavaScript in Java so it can leverage several JavaScript benefits.
(5)In past JavaScript was only interpreted at one time but now it often run through a JIT compiler. On the other hand Java is compiled to bytecode first which is called intermediate form to run by JIT compiler.
(6)Java is mainly designed to support many large application with its robust namespace. But JavaScript doesn't offer it directly so developer have synthesized it.
(7)Java once ran in browsers and servers but is largely limited to servers today. JavaScript once ran only in browsers but is now increasingly used on the server side too.
(8)Both Java and JavaScript supports many of languages. Here Cross-compilers will convert many languages to run on Java’s JVM or JavaScript engines.
(B)JavaScript vs C
(1)C is statically and JavaScript is dynamically typed.
(2)C languages have power to work directly on computer's memory with the help of pointers and JavaScript doesn't have this feature.
(3)In C programming language developer need to manually allocate and deallocate blocks of memory. On the other hand JavaScript will do this automatically.
(4)C program is compiled in advance. On the other hand JavaScript is interpreted and sometime compiled at runtime with the help of JIT compiler(Just in time).
(5)It is necessary to recompile C code when its is moved to different processor and JavaScript doesn't need this.
(6)In C language it offers explicit control of threads but on there hand JavaScript helps users to juggle multiple jobs by splitting tasks into asynchronous functions that is mainly called when data is ready.
(7)C is used mostly where we need very high performance just like it is used for embedded computers and applications just like operating systems. And on other hand JavaScript was first used only in web pages but now it is in new role in server application which is developed through Node.js.
(C)JavaScript vs Ruby
(1)Both of these languages are dynamically typed.
(2)Ruby uses the keyword "end and JavaScript uses curly brackets to define blocks while coding.
(3)In start JavaScript was once limited to run on client browser and on another hand Ruby ran on server with Rails framework.
(4)JavaScript takes many of ideas of Ruby while running in Nodes.js on Server. Ruby use Rails frameworks.
(5)JavaScript takes most of its syntax from Java and C. And Ruby takes most if its features from Perl and Smalltalk.
(6)JavaScript is so popular these days it is general-purpose language. And on another hand Ruby is generally limited to server application by using its Rails frameworks. And we can also use Ruby for their server-supporting command-line applications.
(D)JavaScript vs PHP
(1)JavaScript and PHP both are dynamically typed variables.
(2)JavaScript and PHP both are scripting languages which were originally interpreted at runtime. But now these are often transformed by JIT compiler.
(3)In the starting PHP was mainly designed for servers to assemble different HTML files and JavaScript ran inside the browser on the client. But now JavaScript is also building HTML files on the server too.
(4)PHP is rarely used for anything but assembling HTML. JavaScript is the foundation for increasingly complex interfaces in the browser and server-side stacks integrating business logic and databases.
(5)PHP is a relatively simple language focused on retrieving information from databases and formatting it as HTML. JavaScript is becoming a more general language used for both browser interaction and more general computation.
(E)JavaScript vs C#
(1)C# is statically and JavaScript is dynamically typed.
(2)C# is strongly typed but JavaScript is not.
(3)C# is compiled to bytecode first and then which is an intermediate form to run by JIT compiler. JavaScript in past was only interpreted but now it is often run through a JIT compiler.
(4)C# has feature that it support both operator and conversion overloading. But JavaScript doesn't have this.
(5)C# have another feature like it gives programming explicit control over threading same as Java do. JavaScript hides much of this with its call-and-response function structure.
(6)C# has one of powerful .NET component that is LINQ which adds native data querying capabilities. On the other hand JavaScript has a separate libraries which can cover different functionality one of them is Underscore.js.
(F)JavaScript vs Python
(1)Python was mainly design to run from the command line to support servers. JavaScript was mainly designed to support HTML pages in the browser.
(2)Python use indentation and whitespace while doing code and JavaScript will uses curly brackets to designate blocks of code.
(3)Both of these languages are popular in larger communities now.
(4)JavaScript is found now on servers and on some other locations. Python is mainly used as data processing language in social science.
(5)Python has feature to use flexible parameter blocks for methods. But on another hand JavaScript always insists all parameters must be specified.
(6)Python responds to function calls only. But JavaScript code is mainly often driven by events such as mouse click or any keystrokes.
(7)JavaScript library mainly designed to do changes in HTML in the browser. There are many of Python libraries which are forced on data processing and analysis. | |
