Are javascript and asp both scripting languages?

Javascript and asp are both scripting languages. JavaScript is a browser-side scripting language that is often used to add a variety of dynamic functions to web pages to provide users with smoother and more beautiful browsing effects; while asp is a server-side scripting language that can be used to create dynamic interactive web pages. and build powerful web applications.

Javascript and asp are both scripting languages. JavaScript is a browser-side scripting language, while asp is a server-side scripting language.

Introduction to JavaScript

JavaScript is a client-side (browser-side) scripting language that is object- and event-driven and has relative security. , is also a scripting language widely used in client-side Web development. It has been widely used in Web application development. It is often used to add various dynamic functions to web pages and provide users with smoother and more beautiful browsing effects.

Originally designed by Brendan Eich of Netscape, it is a dynamic, weakly typed, prototype-based language with built-in support classes. JavaScript is a registered trademark of Sun Microsystems (acquired by Oracle). Ecma International developed the ECMAScript standard based on JavaScript.

The complete JavaScript implementation consists of three parts: ECMAScript, Document Object Model, and Browser Object Model.

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

• Web application development: The web pages we browse in daily life are It is composed of HTML, CSS, and JavaScript. Through JavaScript, the style of elements in the web page can be updated in real time, and the interaction between people and the web page can be realized (such as monitoring whether the user clicks the mouse or presses a certain button, etc.), and can also Add some cool animations to web pages;

• 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: Those small games we have played on the web can all be played using JavaScript. Implementation;

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

#asp introduction

ASP stands for Active Server Pages, which is a server-side scripting environment developed by Microsoft. , can be used to create dynamic interactive web pages and build powerful web applications.

When the server receives a request for an ASP file, it processes the server-side script code contained in the HTML web page file that is used to build the file that is sent to the browser. In addition to server-side script code, ASP files can also contain text, HTML (including associated client-side script) and COM component calls.

ASP is simple and easy to maintain, and is the choice for small page applications. When using DCOM (Distributed Component Object Model) and MTS (Microsoft Transaction Server), ASP can even implement medium-sized enterprise applications. .

The difference between javascript and asp

ASP is executed by the server and therefore allows processing of HTTP request headers (cookies, web page references, user agent characters Strings and other personal information sent by the browser when requested, etc.), connect to databases and run on them, read or write log files, etc., and even run some programs on the server.

Thus, it can generate dynamic HTML content and serve it to the user's browser. For example, a login page requires server-side scripting (in ASP, PHP...) to check the validity of login and password (fixed text, information from database...) and generate appropriate HTML content.

JavaScript, on the other hand, has limited access to HTTP headers and cannot perform any operations on the server side (because it runs on the visitor's browser).

However, it can respond to and interact with user actions on web pages generated by the server (the server tells the browser what options are available to the user and what should be done in response to the user's actions).

Javascript is more limited, but it provides the tools to extend the behavior of a web page when the server has finished processing and lost control of it. Basic functionality of verification.
