What is JavaScript

JavaScript is a text-based dynamic programming language that provides a structure and style with HTML and CSS to make a web page interactive. JavaScript uses both server-side and client-side to make interactive web pages.

Someone makes a structure and includes a unique style using HTML & CSS. This is a static web page when you want to add a Search box, timely content updates like Facebook or Twitter news feed, 2D or 3D graphics animations, scrolling system, interactive map and calendar, and more. Here involves JavaScript to make these systems on your web page or website.

There are three fundamental basic languages to make a web page, these are-

  1. HTML- HyperText Markup Language is a programming language that helps to make a structure of a web page. Its fixed position includes website elements like paragraphs, headings, titles, forms, images, audios, videos and more.
  2. CSS – Cascading Style Sheets is another programming language that provides a web page unique style like web page height, weight, font-family, font-size, bg color, font-color, letter spacing, multiple columns, and more.
  3. JavaScript – JS is a scripting programming language that makes a web page dynamic like updating contents, animations, controlling media, calculateing, manipulating, and validating data and more.

Using these 3 languages to create dynamic content that you provide an output it’s called a web page. When connected to multiple web pages a single domain name system is called a website.

What you need to learn to be JavaScript designer

As a JavaScript designer you must to learn these fundamental essential section here include these section that complete this task that like-

  1. Variable – JavaScript variable contains its storage data values that like work. Suppose a, b and c are three variables. These are work in JavaScript this process- 

Ver a=9;

Ver b=10;

Ver c=a+b;

Include this on coding like this

<!DOCTYPE html>

<html>

<body>

<h2>JavaScript Variables</h2>

<p>In this article, a, b, and c are variables.</p>

<p id=”demo”></p>

<script>

var a = 9;

  var b = 10;

var c = a + b;

document.getElementById(“demo”).innerHTML =

“The value of c is: ” + c;

Ver b=2; /*this is the number of without decimals*/

Showing on this number on your browser with single coding like-

<!DOCTYPE html>

<html>

<body>

<h2>JavaScript Numbers</h2>

<p>Numbers can be written with or without decimals:</p>

<p id=”demo”></p>

<script>

var a = 2.12;

var b = 2;

document.getElementById(“demo”).innerHTML = a + “<br>” + b;

</script>

</body>

</html>

This showing up out put a browser like

  1. Objects- When you have a clear concept of a JS variable then you assign a car that is called objects. Objects and variables work the same but objects contain many values of JavaScript. This works-

Ver car =”Fiat” ;

Including single webpage like this-

<!DOCTYPE html>

<html>

<body>

<h2>JavaScript Variables</h2>

<p id=”demo”></p>

<script>

var car = “Fiat”;

document.getElementById(“demo”).innerHTML = car;

</body>

</html>

Output of these object on your browser-\

  1. Array – This array is used for multiple variable values at a  time. It look like

Ver cars=[“WigMarketing”, “dimpim”, “Newspaper”];

Set up this array on single column look like this coding

<!DOCTYPE html>

<html>

<body>

<h2>JavaScript Arrays</h2>

<p id=”demo”></p>

<script>

var cars = [“WigMarketing”, “dimpim”, “Newspaper”];

document.getElementById(“demo”).innerHTML = cars;

</script>

</body>

</html>

Output :

  1. Function
