The examples in this article summarize the way JavaScript creates objects. Share it with everyone for your reference, the details are as follows:
Subconsciously, JavaScript cannot be regarded as an object-oriented language. If it is, it can only be said to be a language that tends to be object-oriented. At least it does not fit well with the three most basic characteristics of object-oriented (inheritance, encapsulation, and multiplexing). state), of course many people think that JavaScript is an object-oriented language, and they seem to be right, because object-oriented can also be implemented in JavaScript. For example, inheritance and encapsulation can also be implemented in JavaScript, but is it easy to implement? ?So I feel very confused. I saw a netizen on the Internet commenting very well, "Object-oriented is just an idea, and the language can only say whether it supports object-oriented features well." If you have a certain understanding of object-oriented, you can also write object-oriented programs in C program, the same is true for javascript. So I can’t say that JavaScript is an object-oriented language. Haha, I think I’m a novice and I don’t dare to make such claims. Let’s take a look at the code:
1. Use json to create objects
var company = {}; company.name= '华为'; company.address = '北京'; company.produce = function(message) { alert(message); }
2. Use the Object type in JavaScript
company= new Object(); company.name= '淘宝'; company.address = '杭州'; company.produce= function(message) { alert(message); }
3. Generate objects by creating functions
company = function() { this.name = '新浪'; this.address = '北京'; this.produce = function(message) { alert(message); } }
4. Use the browser window object
window.name = '腾讯'; window.address = '北京'; window.produce = function(message) { alert(message); }
Extension:
1. Object copy
emptyObject = new Object(); company.apply = function(o, c,) { if(o && c && typeof c == 'object') { for(var p in c) { o[p] = c[p]; } } return o; }; emptyObject = Ext.apply(emptyObject,company);
2. Object copy (function method)
var copyOO = new Function(); copyOO.prototype = company; var newcopyOO = new copyOO();
I hope this article will be helpful to everyone in JavaScript programming.

JavaScript runs in browsers and Node.js environments and relies on the JavaScript engine to parse and execute code. 1) Generate abstract syntax tree (AST) in the parsing stage; 2) convert AST into bytecode or machine code in the compilation stage; 3) execute the compiled code in the execution stage.

The future trends of Python and JavaScript include: 1. Python will consolidate its position in the fields of scientific computing and AI, 2. JavaScript will promote the development of web technology, 3. Cross-platform development will become a hot topic, and 4. Performance optimization will be the focus. Both will continue to expand application scenarios in their respective fields and make more breakthroughs in performance.

Both Python and JavaScript's choices in development environments are important. 1) Python's development environment includes PyCharm, JupyterNotebook and Anaconda, which are suitable for data science and rapid prototyping. 2) The development environment of JavaScript includes Node.js, VSCode and Webpack, which are suitable for front-end and back-end development. Choosing the right tools according to project needs can improve development efficiency and project success rate.

Yes, the engine core of JavaScript is written in C. 1) The C language provides efficient performance and underlying control, which is suitable for the development of JavaScript engine. 2) Taking the V8 engine as an example, its core is written in C, combining the efficiency and object-oriented characteristics of C. 3) The working principle of the JavaScript engine includes parsing, compiling and execution, and the C language plays a key role in these processes.

JavaScript is at the heart of modern websites because it enhances the interactivity and dynamicity of web pages. 1) It allows to change content without refreshing the page, 2) manipulate web pages through DOMAPI, 3) support complex interactive effects such as animation and drag-and-drop, 4) optimize performance and best practices to improve user experience.

C and JavaScript achieve interoperability through WebAssembly. 1) C code is compiled into WebAssembly module and introduced into JavaScript environment to enhance computing power. 2) In game development, C handles physics engines and graphics rendering, and JavaScript is responsible for game logic and user interface.

JavaScript is widely used in websites, mobile applications, desktop applications and server-side programming. 1) In website development, JavaScript operates DOM together with HTML and CSS to achieve dynamic effects and supports frameworks such as jQuery and React. 2) Through ReactNative and Ionic, JavaScript is used to develop cross-platform mobile applications. 3) The Electron framework enables JavaScript to build desktop applications. 4) Node.js allows JavaScript to run on the server side and supports high concurrent requests.

Python is more suitable for data science and automation, while JavaScript is more suitable for front-end and full-stack development. 1. Python performs well in data science and machine learning, using libraries such as NumPy and Pandas for data processing and modeling. 2. Python is concise and efficient in automation and scripting. 3. JavaScript is indispensable in front-end development and is used to build dynamic web pages and single-page applications. 4. JavaScript plays a role in back-end development through Node.js and supports full-stack development.
