The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful for you to answer the doubts about "how to understand javascript scripting language". Next, please follow the editor to study!

Javascript is a cross-platform interpretive, dynamic, weakly typed, prototype-based, network-based scripting language. Javascript has been widely used in Web application development, often used to add a variety of dynamic functions to web pages to provide users with a more smooth and beautiful browsing effect.

The operating environment of this tutorial: windows7 system, javascript1.8.5 version, Dell G3 computer.

JavaScript is a dynamically typed, weakly typed, prototype-based language. Its interpreter, known as the JavaScript engine, is a part of the browser and is widely used in the client scripting language. It was first used on HTML pages to add dynamic functions to HTML pages.

JavaScript is a scripting language belonging to the network, which has been widely used in Web application development. It is often used to add a variety of dynamic functions to web pages and provide users with a more smooth and beautiful browsing effect. Usually JavaScript scripts implement their own functions by embedding them in HTML.

JavaScript is a cross-platform interpretive language that does not need to be compiled in advance and can run under a variety of operating systems.

JavaScript has the following characteristics:

1) interpretive scripting language

JavaScript is an interpretive scripting language. Unlike C, C++ and other languages that need to be compiled and then run, code written with JavaScript does not need to be compiled and can be run directly.

2) object-oriented

JavaScript is an object-oriented language, using JavaScript can not only create objects, but also manipulate and use existing objects.

3) weak type

JavaScript is a weakly typed programming language with no strict requirements on the data types used. For example, you can initialize a variable to any type, or you can change the type of the variable at any time.

4) dynamic

JavaScript is an event-driven scripting language, which can respond to user input without the help of a Web server. For example, when we visit a web page, when we click on the web page or scroll through the window through the mouse, we can respond to these events directly through JavaScript.

5) Cross-platform

JavaScript is independent of the operating system and can be run in a browser. So a JavaScript script can be run on any system after it has been written, as long as the browser on the system supports JavaScript.

Why learn JS?

JS is the most popular and widely used client scripting language at present. It plays an important role in the field of Web development and is one of the necessary skills to become an excellent front-end engineer.

Learning JS has the following advantages over other programming languages:

JavaScript is the most popular client-side scripting language, which is easy to learn. After you have learned, you can use some JavaScript-based frameworks (such as JQuery, Node.js) to develop front-end or back-end applications

JavaScript can be run in a Web browser, so to learn JavaScript, you do not need to configure any special running environment

JavaScript is widely used, such as mobile application development, desktop application development, Web game development and so on, which provides more job opportunities for JavaScript programmers.

JavaScript has a large number of high-quality frameworks and libraries that can greatly reduce your development time.

What can JS do?

JavaScript can be used in various areas of Web development, such as:

Web application development: the web pages we browse in our daily life are made up of HTML, CSS and JavaScript. Through JavaScript, we can update the style of the elements in the web page in real time, and realize the interaction between people and the web page (such as monitoring whether the user clicked the mouse or pressed a button, etc.), and can also add some cool animation to the web page.

Mobile application development: in addition to Web application development, JavaScript can also be used to develop applications on mobile phones or tablets, and we can also use some excellent frameworks (such as React Native) to make development easier

Web games: the Mini Game that we have played on the web page can be implemented using JavaScript

Back-end Web application development: in the past, we all used JavaScript to develop the front-end part of Web applications, but with the emergence of Node.JS (a JavaScript runtime environment), JavaScript can also be used to develop the back-end part of Web applications.

At this point, the study on "how to understand javascript scripting language" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
