Java Script VS Java Discussion Board Response I’ve provided 2 discussions below that need to be responded. The discussion is the following “How would explain the differences between JavaScript and Java Code to a new student. Why do we have the two and why do most programmers believe that there is no different between the two?”.

1-)Java VS. Javascript

Java and JavaScript are, in truth, two distinct JavaScript programming languages. Java and JavaScript do share a brief history together during the early Netscape days of the internet, which explains the similar names. Java is a programming language that produces software for multiple platforms. When a programmer writes a Java application, the compiled code known as bytecode runs on most operating systems, including Windows, Linux and Mac OS. Javascript is a scripting languages, primarily used on the Web. It is used to enhance HTML pages and is commonly found embedded in HTML code.

MAJOR SIMILARITIES

Object-Oriented Programming. Both languages require the developer to code in terms of objects and their relationships to one another. By extension this gives both languages access to techniques like inheritance, encapsulation, and polymorphism.

Front-End Development. Both languages can be used in aspects of front-end development. JavaScript can be embedded directly into HTML, implemented as a framework or library; Java can be used as a Java applet.

Back-End Development. Both languages can be used on the server-side. Java has long been used to power back-end technologies like Apache, JBoss, and WebSphere. Node.js has become a launch pad for JavaScript-powered servers.

MAJOR DIFFERENCES

Compiled vs. Interpreted. Java is considered a compiled programming language. JavaScript is considered an interpreted scripting language.

Static vs Dynamic Type Checking. Java uses static type checking, where the type of a variable is checked at compile-time. The programmer must specify the type (integer, double, string, etc.) of any variable they create. JavaScript, like most scripting languages, uses dynamic typing, where type safety is verified at runtime. It is not required for a programmer to specify the type of any variable they create. There are many pros and cons for these two paradigms, but the primary advantage of static type checking is that type errors are caught early in development, and because the compiler knows exactly what data types are being used, code typically executes faster or uses less memory. The primary advantage of dynamic type checking is programmer productivity—you are free to assign types at your leisure.

2-)Hello everyone,

JavaScript is a lightweight programming language “scripting language”and used to make web pages interactive. It can insert dynamic text into HTML. JavaScript is also known as browser’s language.

JavaScript (JS) is not similar or related to Java. Both the languages have a ‘C’ like a syntax and are widely used in client-side Web applications, but there are few similarities only.

Java is an object-oriented programming language and have virtual machine platform that allows you to create compiled programs that run on nearly every platform. Java promised, “Write Once, Run Anywhere”.

Few differences between Java and JavaScript:

JavaScript:

JavaScript is an object- based scripting language.

JavaScript code run on browser only as JavaScript is developed for browser only.

JavaScript requires less memory therefore it is used in web pages.

JavaScript has event-based approach to concurrency.

Java:

Java is an object -oriented programming language.

Java applications can run in any virtual machine (JVM) or browser.

Java program uses more memory.

Java has a thread -based approach to concurrency.

When you’re new to programming and hear words like Java and JavaScript (JS), you’ll naturally want to make an association between them.However, both languages came out, almost back-to-back, in the same year.

New learners always trying to make sense of the world, looking for patterns and correlations, and it’s sometimes easy to see a pattern where there isn’t one. In this particular case, it may seem like JS is derived from Java. But both are entirely different.
