SmartJS has a lot of content planning, and it cannot be completed in a short time. Currently, the functions are accumulated one by one in small versions.
The content released in the first version 0.1 is mainly to implement some support for front-end aspect-oriented programming (AOP).
1. PromiseEvent
Callback management based on events and promises, similar to jquery callbacks, but with functions such as result delivery, priority, event parameters, promise control, etc.
2. Trigger
Trigger, apply trigger (aop) function on the object, the target object will have method injection function (based on promiseEvent), the injection types are before, after and round;
3. FlowController
Process/life cycle controller, controls the execution and flow of the process, based on Trigger
4. Commonly used methods;
//Merge the default data method, copy the empty content of obj from defObj; it is not the same as jquery's $.extend, only non-existing data will be added
st.mergeObj(deep, obj, defObj, exclude)
//Inject the method into the target object method and return the result
st.injectFn(target, name, fn, before,stopOnFalse)
//Merge method, return result
st.mergeFn(fn, mergeFn,stopOnFalse)
In addition, I would like to state that I am very sorry that the smartUI2.0 promised before has not been completed. My ideas have been changing, and I have found that I have less and less time at my disposal in the past two years. However, smartjs's subsequent planning will also include UI content, which is equivalent to merging smartUI into Smartjs.
Later preview: In smartjs version 0.2, some content supported by oop will be added.
Finally, the smart address is attached, which contains a relatively rich set of test cases. Regarding the API, the blog will be updated to explain them one by one.

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.

C 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'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.

The 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 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 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.
