What is javascript?

What is JavaScript

JavaScript can be called a multi-paradigm language. It has support for many programming methods. For example, object-oriented, functional and imperative.

This type of programming is not directly related to java. The main syntax of this programming language is the C language, as well as C++.

The basis of browser web pages is HTML code, with which programmers add various interactive elements to the pages.

If javascript is disabled in the browser, interactive elements will not work.

This type of programming language appeared thanks to the joint work of Sun Microsystems and Netscape.

Initially, JavaScript was called LiveScript, but after the Java language became popular among programmers, development companies decided to rename it.

Netscape's marketing department believed that such a name would increase the popularity of the new programming language, which, in fact, happened.

Let us remind you that JavaScript is not directly related to Java. These are completely different languages.

Why should you learn JavaScript?

JavaScript is one of the 3 web developer languages

Web developers need to know:

1. HTML to define the content of web pages

2. CSS for web page layout markup

3. JavaScript to program web page behavior

The JavaScript tutorial works with HTML and CSS.

What did you think?

JavaScript and Java are completely different languages, both in concept and design.
JavaScript was invented by Brendan Eich in 1995 and became an ECMA standard in 1997. ECMA-262 is the official name of the standard. ECMAScript is the official name of the language.

You can read more about the different versions of JavaScript in this chapter JS Versions.

JavaScript Features

This programming language has an unlimited number of possibilities due to its versatility.

The main aspects of application are mobile applications for smartphones, interactive web pages of sites and services.

Most of the innovation was brought about by the AJAX company joining the project, which provided the features used in the language today.

To save traffic and increase ease of use, JavaScript provides the ability to change pages of sites and services in small parts, unnoticed by the user online.

This does not require turning off the site while editing or adding new information.

Changes happen immediately, without requiring a page refresh or reload.

The JavaScript feature may be disabled for various reasons.

It is possible that the previous user may have intentionally disabled it since it was not required for web browsing. The shutdown could also happen on its own.

Disabling javascript may prevent some links from opening. Below we will look at ways to enable this function in popular browsers.

Basic Features of JavaScript

JavaScript is a language that has the following features:

• High level. It gives the programmer abstractions that make it possible to ignore the specifics of the hardware on which JavaScript programs are executed. The language automatically manages memory using a garbage collector. As a result, the developer can focus on solving the problems facing him without being distracted by low-level mechanisms (although, it should be noted, this does not eliminate the need for rational use of memory). The language offers powerful and convenient tools for working with various types of data.
• Dynamic. Unlike static programming languages, dynamic languages ​​are able, during program execution, to perform actions that static languages ​​perform during program compilation. This approach has its pros and cons, but it gives the developer such powerful features as dynamic typing, late binding, reflection, functional programming, changing objects at runtime, closures, and much more.
• Dynamically typed. Variable types are not required to be specified during JS development. In the same variable, for example, you can first write a string and then an integer.
• Weakly typed. Unlike strongly typed languages, weakly typed languages ​​do not force the programmer, for example, to use objects of certain types in certain situations, performing implicit type conversions if necessary. This gives more flexibility, but JS programs are not type safe, which makes type checking more difficult (TypeScript and Flow are aimed at solving this problem).
• Interpretable. It is widely believed that JavaScript is an interpreted programming language, which means that programs written in it do not need to be compiled before execution. In this regard, JS is contrasted with languages ​​such as C, Java, Go. In practice, browsers, to improve program performance, compile JS code before executing it. This step, however, is transparent to the programmer and does not require additional effort from him.
• Multi-paradigm. JavaScript does not force the developer to use any particular programming paradigm, unlike, for example, Java (object-oriented programming) or C (imperative programming). You can write JS programs using the object-oriented paradigm, in particular, using prototypes and classes that appeared in the ES6 standard. JS programs can also be written in a functional style, due to the fact that functions here are first-class objects. JavaScript also allows working in the imperative style used in C.

Yes, by the way, it should be noted that JavaScript and Java have nothing in common. These are completely different languages.

Understanding JavaScript

JavaScript is one of the most popular programming languages ​​in the world.
Created more than 20 years ago, it has come a long way in its development. JavaScript was intended to be a scripting language for browsers. At the very beginning, he had much more modest capabilities than now. It was mainly used to create simple animations, such as drop-down menus, and was known as part of Dynamic HTML technology (DHTML, dynamic HTML). Over time, the needs of the web environment grew, in particular, new APIs appeared, and JavaScript needed to keep up with other technologies to support web development.

These days, JS is used not only in traditional browsers, but also beyond them. In particular, we are talking about the Node.js server platform, the possibilities for using JavaScript in the development of embedded and mobile applications, and solving a wide range of problems for which JavaScript has not been used before.
