Javascript is an object-oriented scripting language that can be used for both frontend and backend purposes. It can be used as a part of web pages, server (Node.js) and database (MongoDB). Javascript is easy to set up and supported by most modern web browsers. It enables you to dynamically update contents, control multimedia, animations, 2D/3D graphics, video players, interactive maps and many more. This mode of javascript is referred to as client-side javascript.

Comparison of Javascript

Here is the comparison of javascript with Java,  PHP, and Python.

Java :

Introduction

Java is the combination of programming language and a platform. Java is object-oriented, reliable, secure and easy to use language. It is mostly known for its simple, dynamic and high-performance nature. It should be executed through a cross-platform compatible Java Virtual Machine (JVM) for which Java has its own runtime environment i.e JRE and API. Java has a huge range of application and can be used everywhere including web application, desktop application, mobile phones, satellites and other electronic devices.

Java Vs Javascript: Major similarities

Despite their names being similar, Java and javascript are quite distinct and are incomparable. However, when compared from a web development perspective, top-level similarities can be found.

  • Both are an object-oriented programming language. So, the fundamental OOP concepts must be known by both the developers.
  • Both languages can be used for Front-end development. JavaScript can either be embedded directly in HTML or implemented as a library. Java can be used as a Java Applet.
  • Both languages can be used for back-end development. Node.js is the most popular and powerful server-side environment. While Java has been used for back-end technologies for a long period of time that uses Apache, JBoss, and Websphere.

Java Vs Javascript: Major differences

There is a famous quote by Chris Heilmann, “Java is to javascript what car is to carpet “. This quote illustrates how different java and javascript are.  Here are some points to prove this statement :

  • Java was created by Sun Microsystems (now known as Oracle) while Javascript was developed by Netscape (now known as Mozilla). “Javascript” is a trademark licensed from Sun Microsystems that described the Netscape’s implementation of the language. Netscape submitted the language as standardization of ECMA and was stuck with the name “ECMA Script” because of trademark issues. This is formally known as “JScript” but practically known as Javascript.
  • Java is compiled programming language which is compiled into bytecode. In contrast, javascript is interpreted scripting language which can be interpreted directly into the browser.
  • Java is a static language where the type of variable is checked during the compile time. Here, during the variable creation, the type of the variable must be specified as integer, double or string. On the other hand, Javascript is a dynamic language. The compiler knows exactly what types of a variable is being used so, we don’t have to specify the type of any variable.
  • Java uses class-based inheritance which is a top-down hierarchy where all the properties are defined in a class and are inherited by a member of a class.  while JavaScript is prototype based where all objects can inherit directly from others. Here, the hierarchy is accomplished by assigning an object as a prototype with a constructor function.
  • The Java-based project is used to create Android apps, web apps, Scientific Computing, General hardware programming including Server-Side Technologies like Apache and GlassFish. Likewise, Javascript allows the creation of a dynamic Single page application, front-end application from Angular, Jquery, React, a Server-side application from Node.js, MongoDB, Express and mobile app development through React Native.

PHP

Introduction

PHP (Hypertext Preprocessor) is a general-purpose scripting language. PHP can handle forms, save data to a file, return data to the user, gather data from files and many more. The popular content management system (CMS)  like WordPress, Drupal, and Joomla runs on PHP, which is used to create a majority of the website on the web. From a simple blog to the small business owner trying to set up the landing page, a CMS is an easiest and cheapest solution to set up an online presence. It is also integrated with a number of popular databases like PostgreSQL, Oracle, SQL, MYSQL, and others.

JavaScript vs PHP: Major similarities

Both PHP and javascript are used to create a majority of the website. Javascript on the front side and Php on the backend. These have led to the development of huge libraries, frameworks and community support for these two languages. However, with the introduction of Node.js in 2009, Javascript can be used in server-side as well.

Some major similarities between JavaScript and PHP are :

  • Both PHP and Javascript are scripting language. They can be run in their respective runtime environments. Browser for javascript and server for PHP. Scripts are much easier to use and favor the productivity of the programmers. So both languages are great for beginners.
  • Both JavaScript has first-class functions, where those functions themselves are values.
  • Both PHP and Javascript are open source. The existing code could be used easily by anyone in both the languages.

JavaScript vs PHP: Major differences

PHP is a server-side scripting language while Javascript is more of a general-purpose language that can be used both on the client and on the server side. Let’s look more at the key differences between these two scripting languages.

  • Php doesn’t execute within a browser’s window whereas JavaScript executes within a browser’s window.
  • PHP can be embedded only with HTML while Javascript can be combined with HTML, XML, AJAX.
  • In PHP, the written codes are available only after the interpretation of the server. In Javascript, the code can be viewed even after the output is displayed.
  • PHP is used to produce web pages, read and deploy the databases, import all those files available on the server and receive files of data from further domains. On the other hand, JavaScript can import files by mentioning the URL in the browser where the information is available.
  • Php is conceptually simple to use than Node.js. In PHP, we just need some codes that should be wrapped between the PHP tags to set up a server.  A web server like MYSQL along with PHP will be able to interpret the file and display web pages on your browser. In Node.js server a line of codes is required along with core concepts of closures and working model of call back functions.
  • PHP uses multithreaded, blocking I/O to carry out multiple tasks in parallel. JavaScript uses tricks like event loop along with Node clustering to achieve a single thread, event-driven and nonblocking I/O execution model.
  • JavaScript’s standard libraries are far more consistent than the standard library of PHP regarding its naming conventions.

Python :

Introduction

Python is general-purpose, object-oriented and high-level programming language. It is easy to learn. Elegant syntax and dynamic typing make Python an ideal language for creating a rapid web application. Python can be used to connect database systems; whereby you can read and modify files. It can be used in the world of machine learning, Artificial Intelligence, IOT, embedded systems including data mining and analysis.

JavaScript vs Python: Major similarities:

Python and JavaScript both are a very popular language among the developers. Both are ubiquitous in their own ways and are dominating different areas. Let’s look at some Key similarities between these languages

  • Both are general purpose programming language, that can be used in both client and server side.
  • Both Javascript and Python are dynamically typed. Here, type refers to data types. But Javascript is weakly typed and Python is strongly typed.
  • Both Python and javascript have huge community support. Python has been around for more than 25 years and has accumulated extensive documentation and a much stronger community. Similarly, javascript is the most popular community according to the Github as there are so many projects written in JavaScript as there are so many libraries and frameworks available.

JavaScript vs Python: Major differences

In spite of certain resemblance, Javascript and Python are completely different languages. Both are used for completely different purposes. Let’s have a look at their differences:

    • Python has a clean syntax and more compact code. Therefore, requires a few lines of code as compared with javascript to reach the same result.
    • Javascript uses C notation and curly brackets for closure and blocks while python uses spacing.
    • Python supports actual class while Javascript is prototype based.
    • Use of javascript increases the speed of the web apps and is more suitable for real-time application such as chat apps. Python is slow initially and doesn’t do well with the high graphics app.
    • The scalability in web apps in Node.js can be achieved with the creation of a single thread asynchronous structure with i/o operations. While Python supports asynchronous programming by default.
    • Python takes less time to fix and debug errors as compared to Javascript. Python has greater maintainability and error handling capability.

Conclusion

Despite all their similarities and dissimilarities, all of these languages have their perks and are preferred in their own fields.
