File import solution written in Es6 (detailed interpretation)
This article mainly introduces the relevant information on how to import files written in es6. Friends who need it can refer to
During this period, I learned a little bit about the new specifications of es6, and then I came up with it on a whim. , I want to try to run code written in ES6 in the browser.
Let me talk about my implementation steps first
Translate the ES6 code into ES5;
html file is introduced after translation ES5;
Then run in the browser environment;
Run in the node environment;
Then below are some of my directory structures, a rough preview.
src, es6 development directory
dist, es5 production directory
test, a test Contents
# Then, let’s take a look at what some of the js I developed with ES6 looks like.
file file2
app
test
Then we introduce the translated file in dist into html
Test in the browser. In the test, the module is not introduced, so it executes normally. In the app, the module is introduced, and it is the CommonJS specification, but the browser does not support this specification. Therefore, the error
#If, for the purpose of testing, we add the requireJS file to the html, the browser supports the AMD/CMD standard. Load definitions asynchronously.
However, we found that an error will still be reported, indicating that the syntax is not supported, or the two conflict, because one is AMD and the other is CommonJS.
Since we compile ES6 into ES5 through node, the node module refers to the CommonJS specification, so the syntax of ES5 also belongs to the CommonJS specification, and current browsers and Node does not support ES6 specifications or most of them do not.
Solution
After consulting the information, I found that the dependencies can be merged into one file through the webpack packaging tool, and then introduced into html
The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.

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.

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.
