Both java and javascript languages are multi-paradigm languages, which means these languages support more than one programming style. In other words, Java and Javascript languages support object-oriented programming.

Front-End Development

The use of both languages like java and javascript in the aspect of front-end development. JavaScript programming language can be embedded straightly into HTML and implemented as a library or framework. In addition, the use of Java as a java applet.

Back-End Development

One of the major similarities between java vs javascript is back-end development. Both languages offer server-side support. As well, the java programming language supports major backend technologies like Apache, JBoss, and WebSphere. Node.Js server JavaScript-powered server.

Java vs JavaScript: What’s the difference?

Java and JavaScript play a vital role in the IT industry. In the following section, we will compare the difference between two languages java vs javascript.

Type of language

Java is an object-oriented programming language that is a platform-independent language because it is executed on the Java Virtual Machine.

On the other hand, JavaScript is an object-oriented scripting language that widely helps to make dynamic HTML pages.

Usability

The use of Java programming language is usually in multiple places which include, the creation of desktop applications, Android applications, development of banking, and financial apps.

Whereas the limited use of JavaScript programming language to make web apps more creative and interactive. In addition, it also helps in making animation in HTML.

Application run differently

It is also important to know the difference between Java vs JavaScript about how applications run in both languages. Applications made either using these two programming languages ​​run completely differently.

The Java language develops applications that can be run on browsers and virtual machines. On the other hand, applications built using JavaScript can run on a browser only.

Purpose

The use of Java for all server-side development. The server-side development refers to operations and programs that run on the server. Whereas the use of JavaScript is basically for writing client-side scripts for tasks such as interactivity and JS validation.

Compiled vs Interpreted

Java programming language is a compiling language. On the other hand, JavaScript is an interpreted scripting language.

Moreover, the complied of Java code into bytecode and generally runs on Java Virtual Machine. Whereas the interpretation of JavaScript is directly by a browser in the syntax in which the code is written.

Syntax

 Java programming language uses syntax that is similar to C++ or C programming language. Whereas JavaScript language uses a syntax that is similar to the C language.

Variable

The statically typed programming language of java. In these programs, all the variables need to be delayed before they can be deployed and initialized.

Whereas on the other hand, the dynamically typed language of JavaScript programming.

Concurrency

Java Programming language utilizes a thread-based approach. The division of his approach to the program into small pieces of code in the hardware, which is run concurrently. In addition, this makes it faster and requires less overhead.

Whereas the JavaScript programming language uses an event-based approach. The Event-based approach divides the work by using event loops, callbacks, and queues.

Thus, these are the differences between the java and javascript programming languages.

Conclusion

We hope that this blog on Java vs JavaScript helped you understand the similarities and differences between these two programming languages.

Basically, the use of java and javascript languages widely in the development industry. Both languages provide OOP concepts such as polymorphism, and abstraction to make secure and interactive web applications.

Furthermore, if you learn the Java language then your career moves toward cloud engineering, back-end engineering position, and big data. If you learn JavaScript, you can learn to move toward front-end applications and UI/UX companies that use Node.js.

It increases the demand and popularity of CSS in the modern environment.

In CSS, selectors and combinators hold a unique position. CSS renders you a vast array of options to change and maximize your HTML pages. With the CSS selectors, those options are permitted to target the HTML individual elements to ensure the design is fine-tuned whenever required.

Vast varieties of CSS selectors are accessible – simple selectors, combinators selectors, Pseudo-class selectors, and Pseudo-elements selectors. It allows for fine-grained precision while choosing the elements to style. The CSS selector is the central part of the CSS rule, and thus it needs enough attention.

White characters often surround the combinator.

You have to access two selectors to develop the CSS child selector. The child combinator chooses the elements, which match the first selector’s direct children and the second selector. You can choose only top-level list items with the child combinator. Here is the syntax of the child selector.

element > element {

// CSS property

}

Example

div > p {

background – color: orange:

}

Use of the child selector in CSS

The working process and use of the child selector are straightforward. The selector has two selectors and is separated with the greater than symbol. The first selector indicates the parent element, whereas the second selector defines it as the child element with the style properties. Here is an example.

Div > p

{

font – size : 12px;

}

In the sample code, the <div> element is the parent followed by the <p> child element. The above statement rule makes any paragraph with a font size of 12. The child selector is called the precise operator. It renders certain surprising possibilities when added with the universal selectors.

Example to implement child selector in CSS

div > p

It selects all <p> elements in which the parent is <div> element.

<html>

<head>

<title>

CSS Descendant Selector

</title>

<style>

font-size:26px;

}

CSS

</h2>

<div>

<h2>css</h2>

</div>
