Why do so many people study JavaScript? W hat are its characteristics? This article tells you

Introduction to JavaScript

Web programs, whether C/S (Client/Server) or B/S (Browser/Server) architectures, are divided into server and client programs.

ASP.NET is a powerful tool for server-side program development, but if you want to reduce server burden and traffic, you need to be able to write programs that execute on the client side. S cripting languages are tools that develop client execution programs, making it more efficient to combine APS.NET with scripting languages. S cripting languages of course also include many kinds, such as JavaScript, VBScript, python, and so on. Given the versatility of the JavaScript scripting language, we can make good use of existing resources for larger projects when we develop on the front end.

JavaScript is not really a compiled language, but a complementary language that works with markup language such as HTML to write Web-related programming. J S is a literal language, dynamic type, weak type, prototype-based language, built-in support type. Its interpreter, called the JavaScript engine, is part of a browser that uses the client's scripting language to add dynamic functionality to HTML pages.

JavaScript features

1, scripting language: JavaScript as an explanatory scripting language, in the program running process line by line to explain.

2, object-based: JavaScript is an object-based scripting language that not only creates objects but also uses objects.

3, easy to learn: JavaScript uses variable types are weak types, data types are not too strict requirements.

4. Dynamic: JavaScript is an event-driven scripting language that responds to user input without going through a Web server.

5, cross-platform: JavaScript does not rely on the operating system, only need browser support. Therefore, JS scripts can be used on any machine after writing, and the browser of the premise machine must support the JavaScript scripting language.

That's all you've got about javascript.
