Every Moment is Fresh Beginning

Nowadays modern era we can see everything becoming digital and technology becoming day by day more creative and it helps the new generation. Javascript is one of the programing language where we can create plenty of web pages, mobile apps.

What is JavaScript?

JavaScript is a text-based programming language used both on the client-side and server-side that allows you to make web pages interactive. Where HTML and CSS are languages that give structure and style to web pages, JavaScript gives web pages interactive element s that engage a user. JavaScript is used to program logic for the page layout. For example, HTML is like a car,CSS is like a car design, paint, and decoration, etc and JavaScript is like a car engine (interior logic).

why Javascript is Important? :

js makes responsive design easier. JavaScript has become integral to the Internet experience as developers build increased interaction and complexity into their applications. Search engines, e-commerce, content management systems, responsive design, social media, and phone apps would not be possible without it.

• As a client-side programming language, JavaScripthelps web developers to make web pages more dynamic and interactive by implementing custom client-side script.

• Web developers can't create Modern Applications withoutJavaScript Because:

1.Implement client-side scripts

It is originally designed as a client-side script language. The web developer can easily write and custom client-side scripts in JavaScripts and integrate the script seamlessly into HTML.

2. Write Server-Side Code

The web developer can also write the server-side code in JavaScript by using a cross-platform runtime engine like node.js.

There are also a number of reasons why each modern web developer must know how to leverage all benefits of JavaScript. i.e They can even combine JavaScript, HTML5 and CSS3 to create web pages that look good across browsers, platforms, and devices.

We connect the HTML5 file with JavaScript using script tag and CSS3 with link tag in HTML.

script tag : The <script> tag is used to embed a client-side script (JavaScript). The <script> element either contains scripting statements, or it points to an external script file through the src attribute.Common uses for JavaScript are image manipulation, form validation, and dynamic changes of content.

<script src="app.js"></script>
<link rel="stylesheet" href="style.css" >

3.Simplify Complex Web Application Development

Despite being an interpreted programming language, JavaScript simplifies the development of complex web applications by allowing developers to simplify the application’s composition. The programmers can use JavaScript libraries to create shadow DOM boundaries.

So this was all about javascript importance. if you found this blog helpful do like and comment !! I hope this article is helpful for beginners who want to make their career in the software field they can start from JavaScript.
