Change method: 1. Use the nvm tool and execute the "nvm install specified version number" command to switch to the specified version, and the "nvm install lastest" command to upgrade to the latest version; 2. Use the Node Binary management module, Execute the "n specify version number" command to switch to the specified version.
The operating environment of this tutorial: linux5.9.8 system, nodejs version 12.19.0, DELL G3 computer.
Sometimes we need to be forced to upgrade or downgrade the nodejs version. At this time, the problem arises. How to do it. The summary is as follows. There are two types found in total. The following is the change of the nodejs version in these two cases. Let me talk about it, nvm and n are both nodejs version management libraries, and you can use them all depending on your personal habits.
Method 1, use nvm tool
1), switch to the specified version
nvm install 指定版本号
2), upgrade to the latest version
nvm install lastest
3), upgrade to the stable version
nvm install stable
Method 2: Use n tool
Node Binary management module "n" can be used A very simple way to manage your Node version
1), modify the version
n 指定版本号
2), upgrade to the latest stable version
n stable
3), Upgrade to the latest version
n latest

Python 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.

The shift from C/C to JavaScript requires adapting to dynamic typing, garbage collection and asynchronous programming. 1) C/C is a statically typed language that requires manual memory management, while JavaScript is dynamically typed and garbage collection is automatically processed. 2) C/C needs to be compiled into machine code, while JavaScript is an interpreted language. 3) JavaScript introduces concepts such as closures, prototype chains and Promise, which enhances flexibility and asynchronous programming capabilities.

Different JavaScript engines have different effects when parsing and executing JavaScript code, because the implementation principles and optimization strategies of each engine differ. 1. Lexical analysis: convert source code into lexical unit. 2. Grammar analysis: Generate an abstract syntax tree. 3. Optimization and compilation: Generate machine code through the JIT compiler. 4. Execute: Run the machine code. V8 engine optimizes through instant compilation and hidden class, SpiderMonkey uses a type inference system, resulting in different performance performance on the same code.

JavaScript's applications in the real world include server-side programming, mobile application development and Internet of Things control: 1. Server-side programming is realized through Node.js, suitable for high concurrent request processing. 2. Mobile application development is carried out through ReactNative and supports cross-platform deployment. 3. Used for IoT device control through Johnny-Five library, suitable for hardware interaction.

JavaScript is the core language of modern web development and is widely used for its diversity and flexibility. 1) Front-end development: build dynamic web pages and single-page applications through DOM operations and modern frameworks (such as React, Vue.js, Angular). 2) Server-side development: Node.js uses a non-blocking I/O model to handle high concurrency and real-time applications. 3) Mobile and desktop application development: cross-platform development is realized through ReactNative and Electron to improve development efficiency.

The latest trends in JavaScript include the rise of TypeScript, the popularity of modern frameworks and libraries, and the application of WebAssembly. Future prospects cover more powerful type systems, the development of server-side JavaScript, the expansion of artificial intelligence and machine learning, and the potential of IoT and edge computing.
