JavaScript introduction

Web programs are divided into server programs and client programs, regardless of whether they are Cramp S (Client / Server) or Bamp S (Browser / Server) architecture.

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 can be executed on the client side. Scripting language is a tool that can develop client-side execution programs, and combining APS.NET with scripting languages can be more efficient. Of course, there are many scripting languages, such as JavaScript, VBScript, python, and so on. In view of the versatility of the JavaScript scripting language, we can make good use of existing resources for the development of larger projects when we carry out front-end development.

JavaScript is not actually a compiled language, but a complementary language that works with markup languages such as HTML to write Web-related programming. JS is a literal translation language, which is dynamically typed, weakly typed, prototype-based and has built-in support for types. Its interpreter, called the JavaScript engine, is part of the browser and is used as a client-side scripting language to add dynamic functionality to HTML pages.

Characteristics of JavaScript

1. Scripting language: as an interpretive scripting language, JavaScript is explained line by line in the process of running the program.

2. Object-based: JavaScript is an object-based scripting language, which can not only create objects but also use them.

3. Easy to learn: the variable types adopted by JavaScript are weak types, and there are no strict requirements for data types.

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

5. Cross-platform: JavaScript does not rely on the operating system, only needs the support of the browser. So the JS script can be used on any machine after it is written, as long as the browser of the machine must support the JavaScript scripting language.
