- Building Mega Menus with Flexbox
- Core points Flexbox is a CSS layout model that allows developers to create complex UIs without relying on redundant CSS and JavaScript tricks. It uses a linear layout model, making it easier to layout content horizontally or vertically without spacing calculations. Flexbox can be used to create websites with giant navigation menus. This layout model allows creating simple navigation bars, single drop-down menu segments, and limiting single drop-down menu segments to three columns. The Flex layout is responsive to elements within the container, reducing the need for media queries. The final mega menu created in this tutorial is not fully responsive. The main menu bar will be displayed on a smaller screen, but the giant menu will not be available, only the top links are available

- A Guide to Proper Error Handling in JavaScript
- Key Points Cleverly use the try…catch statement block to effectively manage exceptions, and enhance the debugging process by allowing errors to bubble up to the call stack, thereby displaying errors more clearly. Implement global error handlers (such as window.onerror event) to centralize and simplify error handling for easy management and maintenance in different parts of the application. Use the browser's ability to record detailed error information (including call stack) to improve error diagnosis and a clearer understanding of the source and context of the error. Ensure effective capture and management of asynchronous code by using setTimeout in the try…catch block or using a global error handler suitable for all execution contexts

- BDD in JavaScript: Getting Started with Cucumber and Gherkin
- The benefits of test-driven development (TDD) are well known to improve product quality and development efficiency. Every time you write a code test, you can ensure the correctness of the code and promptly detect possible future code errors. Behavior-driven development (BDD) takes it a step further on this, testing the behavior of the product, not just code, to ensure that the product behavior is in line with expectations. This article will describe how to write BDD-style automated acceptance tests using the Cucumber framework. The advantage of Cucumber is that test cases can be written in concise natural language for easy understanding by non-technical personnel in the project.
