Language TypeIt’s a class based object oriented language.It’s a prototype based scripted language.
Variable DeclarationIt supports static typing and that requires type declaration and variable prior to compilation and execution.It supports dynamic typing. However, in Javascript the type declaration and variable can be defined anytime.
RequirementsTo run a java program, you will require the JDK (Javascript Development Kit).To run JavaScript , you will only require a text editor to write code.
FeaturesIt’s easy to learn and have extensive libraries.It has popular frameworks and is best for front-end development.


Hourly rates of Java and JavaScript developers:

Hourly paces of developers rely upon a few factors, for example, rank level, the degree and intricacy of work, topographical area, and, obviously, the programming language they work with.

In such a manner, Java and JavaScript are very comparable on the grounds that the rates each hour for the two dialects shift somewhere in the range of $61 and $80 universally.

The circumstance, nonetheless, is disparate in Eastern Europe. For instance, rates charged by Ukrainian designers (both Java and JavaScript) range somewhere in the range of $25 and $50 each hour.

Hiring dedicated developers from Asia are viewed as the least expensive ones, implying that they charge the most minimal rates for their work. For instance, if you hire java developer or JavaScript designer from India, then it might cost you just $15-$20 each hour. Nonetheless, a low cost ordinarily goes at an expense for quality.

Looking for Dedicated Developer

What to choose for the next project Java vs JavaScript

Thinking about the contrast between JavaScript and Java, we should summarize what undertakings are better settled utilizing every one of them.

JavaScript is an ideal counterpart for customer-side content creation, sites, and SPA’s just as for portable application improvement utilizing React Native or PhoneGap systems.

Java is an incredible choice for application improvement: versatile for Android, work area, and web venture applications. You can go with Java in the event that there is a requirement for large information investigation and worker side turn of events.

There was some expectation that they’d utilize together and advance together. The two dialects are random.

JavaScript was initially called LiveScript and was renamed when Java was present as a sort of cross-showcasing. They never truly were; Java applets won’t ever take off.

Yet, inside that reach, they could barely be unique. Java specifically, while JavaScript is pitifully composed. The two dialects have some surface similarities. They’re both procedural articles arranged dialects, so they look more like one another (like C++ and C#) than they resemble.
