About building Angular2 development environment (detailed tutorial)
Not long ago, WebStorm's frequent freezes finally made me unbearable. I decided to change to a lightweight editor, tried Emacs, Sublime Text, and finally chose vscode. The following article mainly introduces you to the relevant information about VS Code in the Angular2 development environment construction tutorial. Friends in need can refer to it.
Preface
VSCode is a lightweight editor launched by Microsoft. It adopts the same UI interface as VS and is equipped with appropriate plug-ins. Can optimize the front-end development experience.
Layout: The left side is the file manager used to display all the files and folders to be edited, followed by `Explorer`, `Search`, `GIT`, `Debug`, `Plugins` , the right side is the editing area for opening files, and up to three editing areas can be opened to the side at the same time.
Bottom column: `Git Branch`, `error&warning`, `Encoding format`, etc.
1. Set up the development environment Node Js
The Angular2 development environment mainly relies on Node Js and Npm,
requires node 6.9 .x and npm 3.x.x or above.
To view the version command, use node -v and npm -v.
2. For Angular2 or above, use the Angular CLI command line tool
You can quickly create projects, add files, and perform a host of development tasks, such as testing, packaging, and publishing.
Then install Angular CLI globally.
npm install -g @angular/cli
Note: The installation process may be slow and you need to wait for a few minutes.
3. Create a new project
Run the following commands to generate a new project and the skeleton of the application Code:
ng new my-app
Note: The first installation process is also slow, please wait patiently for a few minutes,
4. Start the development server
Enter the project directory and start the server
cd my-app ng serve --open
ng serve
The command will start Development server that listens for file changes and rebuilds the application when those files are modified.
Use the --open
(or -o
) parameter to automatically open the browser and access http://localhost:4200/
.
5. Open the project in VS Code

JavaScript 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 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.
