JavaScript is considered one of the most powerful programming languages ​​in the world for its strength and effectiveness, and it is used in a large number of applications, including web applications, Android application programming, or even game programming.
What is javascript:
JavaScript is simply a high-level programming language, its primary role is to breathe life into web pages written in HTML and make them dynamic and gives you the ability to control every part of the web page, from forms to links and even some external functions.
Javascript origin:
JavaScript was designed by Netscape to add some liveliness to web pages, of course I can't fail to mention that Java was originally designed by Sun, which is the main owner of the language.

Features of JavaScript:

JavaScript differs from most other programming languages ​​in that it is easy to control, even for people who have not written in any other programming language in their entire life. Quite simply, JavaScript is the air for your page. In addition, it is a programming language that supports OOP as well as a base object, which depends on the presence of some pre-existing classes within the language that can be used easily, such as the window object and the document object.
JavaScript enables handling of events
It does not depend on the type of platform as it supports all operating systems such as Windows and Linux, it does not depend on the type of system as we said. Platform independent JavaScript is language sensitive case, meaning that a word written in lowercase Latin letters is different from the same word written in uppercase.


Why learn JavaScript:
This language provides several advantages for programming and is characterized by great effectiveness and ease of use as well as learning in addition to being characterized by strength .. freedom .. creativity. Because just by writing in HTML, you are bound to keep your page as it is, and it does not change except by changing the code, and this is totally unacceptable in the world of new technology. And with JavaScript, you can even dress your page with a new suit of background colors..and types of fonts..and even images..according to The daily time of the visitor and without any intervention from you! And another important thing.. JavaScript is one of the simplest languages! Everyone can learn it..Yes..everyone..Don't you agree with me, that writing your own code directly is a thousand times better than searching for it on the net. You may not find what you want easily! Or you may not find it at all.

The difference between java and javascript:
Each of them can be used to develop different applications or features for Internet pages, but the code and commands for each of them differ from the other on the one hand. On the other hand, the biggest difference is reflected in the type of applications used; Running Java applications is only done from the desktop or through the web page, and they are independent programs and usually open a separate program window. Therefore, you must install Java on your device to be able to run it. But the advantage of JavaScript is that it is included in all modern browsers and therefore you will be able to use it easily when loading the web page and you will not need to install any other programs on your device. Through JavaScript it is possible to create different applications on the same web page.

So in summary, JavaScript is the programming language that brings your website to life so that the user can interact with the various components that make up your page (eg games, responses when buttons are pressed or data is entered into models, designs, designs, etc.). mobile)
