Java VS Javascript

Java VS Javascript

What Is Java?

Java is a high-level programming language that came into light in 1955 and earlier known as “Oak” and “Green” during initial development. It brought the idea of C and C++ making all the developers easy to code and the main idea behind it was write once run anywhere, Instead of compiling to separate executables for different target platforms, Java source code is bundled in a single JAR file that runs on any all the system, which made java platform independent. Java runs on both virtual machines and web browsers too.

All the works done in Java is possible through Java Virtual Machine (JVM). The JVM finds the JAR record (which is a collection of Java-explicit guidelines), and then the JVM compiles the jar file to the platform-specific instructions at runtime, then the app is executable.

Java in the real world

  1. Android apps — Android was built using Java so it is the official language that can be used for Android app development making it more fastest in performance and native experience.
  2. Desktop apps — Java is available for a desktop app too. Using multiple plugins and frameworks java can be served for desktop applications too.
  3. Enterprise systems — With the availability of high and secure technology java is very much popular for web application building enterprise systems. Making all the industries and banks for enterprise, HR, banking system java is available for all.
  4. Embedded systems —Unlike desktop, mobile, and web app Java is applicable for embedded systems too like digital watches, controllers and traffic lights and etc.

What Is JavaScript?

JavaScript is a scripting language which was evolved from the HTML’s vast limitations. It is a more dynamic language written within HTML. Alongside HTML and CSS, JavaScript is one of the three main pillars of web development. Unlike Java, which is compiled, JavaScript is interpreted and when it is used and loaded in any web browser. Once it is loaded in the browser the full javascript source code interprets it using JavaScript engine.JavaScript is the flexible language in the world which also reveals its popularity.

JavaScript used in the real world.

  1. Web apps — JavaScript can be used for both front-end and back-end web development. The browser-side DOM-manipulation like animation, data insertion, and updates are from From end and similarly data interaction, routing handling falls in the back end which is server-side logic. Some JavaScript frameworks do both, which is called full-stack web development.
  2. Desktop apps — Desktop application can be provided with JavaScript by packaging into standalone desktop software using frameworks like Electron and NW.js (formerly Node-Webkit). This is done by bundling a JavaScript engine inside the executable, which interprets the HTML/CSS/JS within a standalone desktop window.
  3. Mobile apps — Frameworks like React Native and PhoneGap let you create mobile apps using JavaScript. These frameworks tend to fall into two types: those that transpile the JavaScript into native code and those that use a bundled JavaScript engine to render as an app.
