Java vs JavaScript: A Short Comparison

Java vs JavaScript: A Short Comparison

We have already compared PHP and Python, Java and .Net, Kotlin and Java, PHP and Java and some other pairs of popular programming languages. In this blog post, we will talk about Java and Javascript.

Both of these languages have ‘Java’ in their names which sometimes leads to a misconception that they are similar or somehow related to each other. But as Jeremy Keith (a web developer from England) once said, Java is to Javascript as ham is to a hamster. To make sure he was right, let’s now take a closer look at the difference between Java and Javascript.

The Main Features of Java and Javascript

We keep broadcasting the idea that there are no good or bad programming languages but there is always a language that better suits for solving particular tasks. That is why there will be no conclusion on which is better: Java or Javascript but we will highlight the best use cases of each language.

Java

Java is an object-oriented programming language released in 1995. It is compiled and uses mainly JVM (Java Virtual Machine) to execute code. Java supports the static type of checking for programs, so the mistakes and other issues are revealed during the compilation.

It is mostly used for back-end development and is the official language of Android App Development (and also the most popular for developing Android apps). The source code is compiled into an unreadable byte code which enhances its security.

Javascript

Javascript is an object-oriented scripting language that also appeared in 1995. Unlike Java, it is interpreted and is executed in the browser. Supporting the dynamic type of checking, Javascript checks the script on the go, during the execution.

Its main task is to make web pages interactive and to be a tool for the development of client-side scripts or SPA’s (single page applications). The main use purpose of Javascript is front-end development. Its code can be easily read by anyone since it is written in plain text and not compiled.

The Similarities of Java and Javascript

Paying a lot of attention to the differences, we should also talk a bit about what Java and Javascript have in common. Both languages offer a wide range of frameworks and libraries which makes them robust tools for building modern applications.

Despite the fact that Java is mainly used for back-end and Javascript — for front-end, both of them can be effectively utilized either for the client-side or for the server-side development.

Java or Javascript: What to Choose for the Next Project

Considering the difference between Javascript and Java, let’s sum up what tasks are better solved using each of them.

Java is a great option for application development: mobile for Android, desktop and web enterprise apps. You can go with Java in case there is a need for big data analytics and server-side development.

Javascript is a perfect match for client-side scripts creation, websites, and SPA’s as well as for mobile app development using React Native or PhoneGap frameworks.
