JAVA VS. JAVASCRIPT: THE 2021 PERSPECTIVE

Java 

• Object-oriented Programming 
• Standalone language executed by the Java Virtual Machine
• Class-based objects 
• Need entire java development kit
• Support the static type programming 
• Unreadable byte coding type 
• Support class concurrency & maintain parallel concurrency 

JavaScript 

• Client-side scripting language 
• HTML document executed by a web browser, such as Mozilla & Firefox
• Prototype-based
• Need a text editor 
• Support the dynamic type programming 
• Easily readable 
• Support await functions in promises and coding. 

THE FOLLOWING ARE SOME OF THE BENEFITS OF JAVA GIVEN TO PROGRAMMERS: 

• Supports multi-threading 
• Programs can comply with native code 
• Support the process of application development 
• Java APIs can be used as methods or commands.

THE FOLLOWING ARE SOME OF THE BENEFITS OF JAVASCRIPT GIVEN TO PROGRAMMERS: 

• Additional flexibility over Java implementations
• Relatively faster as interpreters can execute the source program code
• Support features, such as dynamic typing  
• Smaller executable program size 
• Compatibility  with a huge variety of applications
