- Three JavaScript Quirks That Java/C Developers Should Know
- Core points Unlike C or Java, JavaScript's scope is function-based, not block-based; variables declared in if or for blocks are promoted to the top of the function or global scope. Elevation in JavaScript means that variables and function declarations are moved to the top of their included scope during compilation, but initialization is not elevated. Functions in JavaScript are treated as first-class citizens, meaning they can be stored in variables, passed as parameters, returned by other functions, and have properties like objects. The with statement (dynamic scope variable) in JavaScript has been deprecated because it may cause the

- Understanding Two-way Data Binding in AngularJS
- Detailed explanation and application of AngularJS two-way data binding: Dynamic business card generator Core points AngularJS's two-way data binding allows changes to update views and vice versa. This is achieved through AngularJS built-in directives such as ng-model and ng-bind. The $scope object in AngularJS plays a crucial role in bidirectional data binding, acting as a bridge between the controller and the view, storing model data and functions. AngularJS combines event and attribute binding and digest cycle mechanism to implement two-way data binding to monitor and update views when data changes. While bidirectional data binding can simplify development by automatically synchronizing views and models,

- AtoZ CSS Screencast: Unicode Range and @font-face
- Summary of key points CSS' @font-face rule allows custom fonts to be used in web design, thereby improving performance and improving typography. Be sure to test these custom fonts on different operating systems and browsers to make sure they appear correctly. The unicode-range property of CSS can be used to limit the character range of custom font applications. This is especially useful for adding special characters or symbols directly to the tag, or using special fonts for specific characters. By using the unicode-range property, you can improve web page performance by ensuring that only the necessary characters are downloaded and used, thereby reducing the amount of data that needs to be loaded. However, it should be noted that not all browsers support this

- Common Pitfalls to Avoid when using HTML5 Application Cache
- Key Points Never include manifest files in the application cache manifest, which creates a loop that will barely inform your website that new cache files are available. Always set the application type manifest in the server's .htaccess file to ensure AppCache is running correctly. If the media type is not set, AppCache will not work. Note that if none of the individual files specified in the manifest file are found or cannot be downloaded, the entire manifest file will be discarded. This is a special behavior of AppCache. After updating the website, always update the manifest file, otherwise the user will not see the changes and will only see the data that was previously cached. You can update the version number or date in the comments in the manifest file,
