Java Vs JavaScript: What’s The Difference?

Java and JavaScript are two of the most popular programming languages in the world. However, they couldn’t be more different!

While Java is generally known for its versatility and object-oriented approach, JavaScript has become a staple for web developers looking to create interactive user experiences. But what sets these two languages apart?

This blog post will explore the differences between Java and JavaScript. Read on to discover which language might be best suited for your next project!

Let’s get started!

Origin and Purpose

Java and JavaScript have different origins and purposes. Java was first created in 1995 by Sun Microsystems as a general-purpose programming language that you could use for:

desktop
mobile
web applications

It was usually designed to be platform-independent so that code written on one system could run on any other method without modification. On the other hand, JavaScript was introduced in 1995 by Netscape Communications Corporation to enhance static HTML pages with interactive elements. Its purpose was to provide dynamic functionality to web pages, such as form validation or animations.

Type of Language

Regarding the type of language, Java and JavaScript differ significantly. Java is a statically typed language. It means you must declare variables with their specific data types before you can use them.

On the other hand, JavaScript is dynamically typed. It also means it allows for more flexibility in coding, as variables do not need to be explicitly declared.

The static typing of Java means it has stricter rules about how code is written and compiled than JavaScript. This results in fewer errors. JavaScript’s dynamic typing makes it easier to write quickly and efficiently. It is because developers don’t have to worry about declaring variable types before use.

Object-Oriented Programming

Object-Oriented Programming (OOP) is a programming paradigm. It focuses on the use of objects to structure code. Java and JavaScript both support OOP concepts but differ in their approach.

Java is a class-based language. It means that everything must be usually defined within a class. A class describes an object’s properties and behaviors. Objects are instances of classes. In Java, inheritance allows for sharing of attributes and methods between classes.

JavaScript is also an object-oriented language. However, it uses prototypal inheritance instead of classical inheritance like Java. Instead of defining classes upfront, JavaScript allows for the dynamic creation and modification of objects at runtime.

File Conversion Functions

Both JavaScript and Java convert HTML to PDF. Java provides several libraries and frameworks that can be used to convert HTML to PDF. One popular library for this purpose is iText.

iText is a free and open-source library that allows you to create and manipulate PDF documents in Java. It has a robust set of features and can handle complex HTML structures.

You can use JavaScript to convert HTML to PDF in the browser using a library like jsPDF. jsPDF is a free and open-source library that allows you to generate PDF documents from HTML or other formats in the browser. It can be used with jQuery or any other JavaScript framework.

Understand the Difference Between Java and JavaScript

Java and JavaScript are two very different programming languages. However, their close similarities in name can often need to be clarified. Java is a class-based, object-oriented language. JavaScript is a scripting language.
