Creating Charting Directives Using AngularJS and D3.js
Article Introduction：Core points
D3.js is a JavaScript library that can be used in conjunction with AngularJS to create interactive real-time charts with SVG (scalable vector graphics). This combination allows developers to create rich web applications with dynamic data visualization.
AngularJS and D3.js can be set in HTML pages to create chart directives. This includes creating AngularJS controllers and instructions and using the controller to save the data to be drawn in the chart. Then, you can use this directive to draw a line chart using D3.js.
The chart can be updated in real time to reflect changes in the underlying data. This can be done by using a collection observer in the instruction to monitor changes in the collection data and then detect

What are CSS preprocessors like Sass or Less?
Article Introduction：CSS preprocessors such as Sass and Less make CSS easier to maintain by introducing variables, nesting, and mixing features. 1. Variables can store colors, font sizes and reused; 2. Mix them into CSS code blocks that allow you to define reusable; 3. Nesting and improving HTML structure visualization, suitable for multi-file complex projects. Both need to be compiled into standard CSS, Sass supports .scss and .sass, and Less uses .less. Sass syntax is more flexible, and Less relies on JavaScript to process. Despite the rise of modern CSS and CSS-in-JS, preprocessors can reduce duplicate code and remain modular in medium and large projects, especially for teams without complex build systems or custom framework themes.

Understanding the autoplay policy changes affecting HTML5 video.
Article Introduction：The core reason why browsers restrict the automatic playback of HTML5 videos is to improve the user experience and prevent unauthorized sound playback and resource consumption. The main strategies include: 1. When there is no user interaction, audio automatic playback is prohibited by default; 2. Allow mute automatic playback; 3. Audio videos must be played after the user clicks. The methods to achieve compatibility include: setting muted properties, mute first and then play in JS, and waiting for user interaction before playing. Browsers such as Chrome and Safari perform slightly differently on this strategy, but the overall trend is consistent. Developers can optimize the experience by first mute playback and provide an unmute button, monitoring user clicks, and handling playback exceptions. These restrictions are particularly strict on mobile devices, with the aim of avoiding unexpected traffic consumption and multiple videos

Performing Background Tasks with HTML5 Web Workers
Article Introduction：WebWorkers is a multi-threaded mechanism provided by the browser, which is used to place time-consuming tasks on the background thread to execute, avoiding blocking the main thread. 1. Worker does not have DOM operation permissions, and can only pass messages through postMessage and onmessage; 2. Creating a Worker requires a separate JS file and instantiated through newWorker(); 3. Common uses include data processing, image audio processing, JSON parsing, game AI computing, etc.; 4. Pay attention to cross-domain restrictions, resource consumption control and compatibility issues when using it. The rational use of WebWorkers can significantly improve web page performance and user experience.
