Use JavaScript to do: 1. Data visualization development; 2. Mobile application development; 3. Server-side development; 4. Full-platform application development; 5. Game development; 6. VR development; 7. Hardware development ; 8. Operating system development; 9. Machine learning development.
The operating environment of this tutorial: windows7 system, javascript version 1.8.5, Dell G3 computer
What can JS do now?
1. Data visualization development
Data visualization is an interactive display mode that is highly respected by everyone nowadays, and Javascript hasECharts, Dygraphs.js, D3.js, InfoVis, Springy.js and other available data A framework for visualization.
2. Mobile application development
PhoneGapwillWebView brings it to mobile applications, and it also brings JavaScript to mobile applications.
3. Server-side development
Because the performance of V8 will JavaScript was brought to a new level, so Node.js was born - both front-end and backend can use JavaScript, and now any web page is inseparable from JavaScript .
4. Full platform application development
One code builds mobile, desktop, Web can be applied on all platforms, and running Ionic on Eletcron means unlimited possibilities.
##5. Game development
If you only stay at ## for web games In the era of #Flash, it would be wrong to think that only Flash can create very gorgeous game special effects. JavascriptYou can also create gorgeous special effects!
##6. VR developmentUse 3D
game engine , such asThree.js, you can also create a 3D world. 
7. Hardware development
Tessel can be done directly in Run JavaScript on the device. You don’t even need a server. Then you can develop it using IDE and libraries just like web development. To upload new firmware, just say tessel#. ##Push instructions.
8. Operating system development
So is it possible to use only Node.jsCreate an operating system? NodeOS Understand that although it uses the Linux kernel to handle various low-level tasks, such as hardware communication, but other than that, it uses Node. js.
9. Machine learning development
UseTensorFlow.js, you can develop machine learning models for image classification, speech recognition or predictive analytics. You can operate in Node.js or in the browser. Machine learning is a very GPU intensive task, but it can be hardware accelerated running in the browser with WebGL. This way you can run a recommendation system that exists entirely on the client side, without expensive server charges, while mitigating privacy concerns.
The above is the detailed content of What JavaScript can do. For more information, please follow other related articles on the PHP Chinese website!
From Websites to Apps: The Diverse Applications of JavaScriptApr 22, 2025 am 12:02 AMJavaScript 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 vs. JavaScript: Use Cases and Applications ComparedApr 21, 2025 am 12:01 AMPython 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.
The Role of C/C in JavaScript Interpreters and CompilersApr 20, 2025 am 12:01 AMC and C play a vital role in the JavaScript engine, mainly used to implement interpreters and JIT compilers. 1) C is used to parse JavaScript source code and generate an abstract syntax tree. 2) C is responsible for generating and executing bytecode. 3) C implements the JIT compiler, optimizes and compiles hot-spot code at runtime, and significantly improves the execution efficiency of JavaScript.
JavaScript in Action: Real-World Examples and ProjectsApr 19, 2025 am 12:13 AMJavaScript's application in the real world includes front-end and back-end development. 1) Display front-end applications by building a TODO list application, involving DOM operations and event processing. 2) Build RESTfulAPI through Node.js and Express to demonstrate back-end applications.
JavaScript and the Web: Core Functionality and Use CasesApr 18, 2025 am 12:19 AMThe main uses of JavaScript in web development include client interaction, form verification and asynchronous communication. 1) Dynamic content update and user interaction through DOM operations; 2) Client verification is carried out before the user submits data to improve the user experience; 3) Refreshless communication with the server is achieved through AJAX technology.
Understanding the JavaScript Engine: Implementation DetailsApr 17, 2025 am 12:05 AMUnderstanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.
Python vs. JavaScript: The Learning Curve and Ease of UseApr 16, 2025 am 12:12 AMPython is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.
Python vs. JavaScript: Community, Libraries, and ResourcesApr 15, 2025 am 12:16 AMPython and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.
