Java is an object-oriented programming language and is typically used to create applications that operate in a virtual machine or browser. Java is often known as “Write Once, Run Anywhere”. JavaScript is an object-based scripting language.
Java is a stand-alone language where code has to be compiled and is used to perform complex tasks. Java also requires more memory to function. JavaScript is easier in comparison, as the code is all text. JavaScript cannot be used to navigate through more complex tasks and requires lesser memory to operate.
