This article focuses on "whether javascript is a scripting language". Interested friends may wish to take a look at it. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn whether javascript is a scripting language.

1. Javascript is a scripting language.

2. It is also a lightweight programming language.

3. The programming code that can be inserted into HTML page.

4. After JavaScript is inserted into the HTML page, it can be executed by all modern browsers.

Introduction to JavaScript:

JavaScript (JS for short) is a lightweight, interpretive or just-in-time programming language with function priority. Although it is known as a scripting language for developing Web pages, it is also used in many non-browser environments. JavaScript is based on prototype programming, multi-paradigm dynamic scripting language, and supports object-oriented, imperative, declarative, and functional programming paradigms.

JavaScript was first designed and implemented in Netscape Navigator browser by Brendan Eich of Netscape in 1995. Because Netscape works with Sun, Netscape management wants it to look like Java, so it is named JavaScript. But in fact, its grammar style is similar to that of Self and Scheme. [2]

The standard of JavaScript is ECMAScript. As of 2012, all browsers fully support ECMAScript 5.1, and older browsers support at least the ECMAScript 3 standard. On June 17, 2015, ECMA International released the sixth edition of ECMAScript, which is officially called ECMAScript 2015, but is often referred to as ECMAScript 6 or ES2015.

The JavaScript scripting language has the following characteristics:

(1) script language. JavaScript is an interpreted scripting language. Languages such as C and C++ are compiled and then executed, while JavaScript is explained line by line in the process of running the program.

(2) based on object. JavaScript is an object-based scripting language that can not only create objects, but also use existing objects.

(3) simple. The JavaScript language uses weak variable types and does not make strict requirements on the data types used. It is a scripting language based on Java basic statements and control, and its design is simple and compact.

(4) dynamic. JavaScript is an event-driven scripting language that responds to user input without going through a Web server. When visiting a web page, JavaScript can directly respond to these events when the mouse clicks or moves up and down, window movement and other operations in the web page.

(5) Cross-platform. The JavaScript scripting language does not depend on the operating system and only needs the support of browsers. So a JavaScript script can be written and used on any machine, as long as the browser on the machine supports the JavaScript scripting language, and JavaScript is already supported by most browsers. Unlike server-side scripting languages, such as PHP and ASP,JavaScript, are mainly run on users' browsers as client-side scripting languages and do not require server support. So in the early days, programmers preferred JavaScript to reduce the burden on the server, while at the same time brought another problem, security.

With the strength of the server, although programmers prefer to run scripts on the server side to ensure security, JavaScript is still popular for its cross-platform, easy-to-use and other advantages. At the same time, some special features, such as AJAX, must be supported on the client side by relying on JavaScript.

At this point, I believe you have a deeper understanding of "whether javascript is a scripting language". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
