Java and JavaScript are not in the same family of languages but have some similarities. They are like two different sides of a coin. Java was written in 1995 and also the most popular language. Which used for software development. That’s why a Front End Development language ECMA-Script, known as JavaScript. To increase its popularity and it’s the backbone of every website.
Java:
A Java programming language, developed by “Sun Microsystem” in 1995. Java is an object-oriented programming language and also has a virtual machine platform that allows you to create compiled programs that run on nearly every platform. Java promised, “Write Once, Run Anywhere”.
JavaScript:
JavaScript is a lightweight programming language(“scripting language”). Which used to make web pages interactive. It can insert dynamic text into HTML. JavaScript, also known as the browser’s language. JavaScript is not similar or related to Java. Both the languages have a C like a syntax, widely used in client-side Web applications, but there are few similarities only. JavaScript developed by “Netscape”.
