If you are a fan of programming then you should immediately see the yellow color, and you will think about programming quickly. As for those who arrived here in search of what we will talk about, you will join the yellow community after reading these lines with us.
Yes, and as it is no secret to anyone, the yellow leads us directly to thinking about JavaScript. But do you have enough information about it ?! What is different from the rest of the programming languages? In this article, we will learn about the areas of use of JavaScript and its most important features. But let's highlight a simple definition of it so that you have the correct idea about it. 1
What is JavaScript?
Javascript is a high-level programming language commonly used for website development. Netscape developed it as a way to add dynamic and interactive elements to sites.
Javascript is strongly affected by the Java language, is similar in composition to the C language and is based on ECMAScript, which is a programming language developed by Sun Microsystems. Over time it replaced a variety of other programming languages to become a standard for browser programming.
JavaScript development
He invented the Java Brendan Ish language in 1995 under the name Mocha while working for Netscape, drawing inspiration from Java, Scheme and Self.
This language did not receive attention at first, but over time it became a source of interest for many programmers after adding new technologies and support for the Java language and called it JavaScript.
JavaScript features
Javascript is used in programming by the client or what is called the client side, but it is characterized by many technologies and features, which we supply:
Implemented by the client side, for example, you can check the validity of any entries before sending the request to the server.
It is a relatively easy language to learn and close to English.
A separate programming language, not some people think, is related to Java.
Provides greater control services for browsers.
Interactive and fast.
It has rich interfaces and you can drag and drop components to enrich your interface with the required elements.
Functional programming language
JavaScript restrictions
Security Issues: Since most of the code is executed on the user's computer, it can sometimes be exploited for malicious purposes, which causes many people to disable it.
It does not support reading or writing files from the customer's side.
It cannot be used in networking applications because there is no appropriate support available.
It does not support multithreading, a technique in which multiple paths are executed simultaneously on the same processor.
Javascript display varies between different browsers and search engines, which causes the interface and functions to be inconsistent at times.
The difference between JavaScript and Java
The designation of JavaScript must definitely make us believe that JavaScript is linked to the Java language. Although both are C-based and used in client-side web applications, in the following lines we will explain some of the differences between them:
The difference between javascript and javascript
We cannot deny the fact that both JavaScript and Javascript is a programming language used to develop applications or different features of web pages, except that the code for each of them differs from the other.
The biggest difference is the type of application used. Java applications are run either from the desktop or through the webpage, which are standalone programs and usually open a separate program window. If you do not install Java, you will not be able to run its own applications on your device. While JavaScript is usually included in all modern browsers so you will be able to use it easily when loading a web page. Through JavaScript, you can create different applications on the same web page, as you can also develop video games and work on them in the browser window.
Java software is usually based on calculation and logical thinking, and it works on programming from the server side in a large way, while JavaScript is focused on the client side. This makes Javascript faster.
While Java can be used to develop massive programs, it often requires a large memory space, which can cause the computer to run slowly or slow down to another program. On the other hand, JavaScript works with a small amount of memory, so it is widely used on many webpages due to the low memory requirements and the ability to provide many unique features.
