【JavaScript Date Object】
# #Date objectDate object: used to set and get the current time. Date object methods are divided into two types:
One uses local time; One uses world time UTC (that is, if there is "UTC" in the method), it means World time; (based on 0 degrees longitude).
Get the current time of the system:var time = new Date(); console.log(time); 获取具体时间(get)
All get methods have UTC acquisition, except getYear()\getTimes( )
Obtain time other than UTC is world time):get[UTC]FullYear( )——获取年份;
get[UTC]Month( )——获取月份;
get[UTC]Date( )——获取日期;
get[UTC]Day( )——获取星期;
get[UTC]Hours( )——获取小时;
get[UTC]Minutes( )——获取分钟;
get[UTC]Seconds( )——获取秒数;
get[UTC]Milliseconds( )——获取毫秒;
getTime( ):返回Date对象的内部毫秒,这个值没有“UTC”方法;
getTimezoneOffset():返回当前日期的本地表示与UTC表示之间的时间差的值;
getYear( ):返回Date对象的年份值,建议使用get[UTC]FullYear()。
Three ways to set the timeset[UTC]FullYear( )——设置年份; set[UTC]Month( )——设置月份; set[UTC]Date( )——设置日期; set[UTC]Hours( )——设置小时; set[UTC]Minutes( )——设置分钟; set[UTC]Seconds( )——设置秒数; set[UTC]Milliseconds( )——设置毫秒; setTime( ):使用毫秒格式,设置一个Date对象的值; setYear( ):设置年份值,建议使用set[UTC]FullYear()。

Python 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 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.
