After following, you can keep track of his dynamic information in a timely manner
You cannot use == or === directly to determine whether two arrays are equal, because the array is a reference type, and it will return false even if the content is the same; 1. Use JSON.stringify(a)===JSON.stringify(b) to arrays whose elements are basic data types and are consistent in order, but the order of object attributes will lead to unequality; 2. Manual traversal comparisons are used to check lengths and compare elements one by one, which are suitable for basic types and are efficient, but do not support objects or nested arrays; 3. The depth comparison function is implemented through recursion, which can handle object arrays and nested structures, and supports the equality judgment of complex data types; 4. Use the _.isEqual method of the Lodash library to directly perform deep comparisons, which are concise and can be used.

Open your phone's phone or call history app, go to the "Recent" or "Call History" tab, and view the call duration displayed next to each call history (such as "2 minutes and 30 seconds"). Missed calls usually have no time or are marked "Missed". 2. Some devices support clicking or long pressing on the call record to view detailed information, such as the start time, end time and specific time. Samsung mobile phones can select "Call Details" through the three-dot menu to get more information. 3. If you need more detailed call statistics functions, you can choose from third-party applications such as Truecaller, CallRecorder or CallLogPro. These applications usually highlight the call duration and support sorting by time, but you need to pay attention to privacy protection and local laws and regulations. 4. If using Google

To run and wait for multiple goroutines to complete, use sync.WaitGroup. 1. Call wg.Add(1) before starting each goroutine to increase the counter; 2. Call wg.Done() inside the goroutine (recommended to use deferwg.Done()) to notify completion; 3. Call wg.Wait() in the main goroutine to block until all tasks are over. This method is simple and efficient. It is a common practice in Go to handle such scenarios. It is necessary to avoid problems such as calling Add in goroutine, missing Done, copying WaitGroup or improper reuse, and ultimately ensuring that the program is correctly synchronized and exited safely.

Use the poster attribute to display poster images before HTML5 video playback. The method is to add poster="path/to/poster-image.jpg" to the tag; 2. Ensure that the image path is correct and the format is compatible (such as JPEG, PNG or WebP), and match the video size to avoid deformation; 3. The poster image will automatically disappear after the video starts playing. If it is not set or loaded, the browser may display the first frame or blank of the video; 4. The display style of the video element can be controlled through CSS, such as using object-fit:cover to ensure the beautiful layout; 5. If dynamic control is required, JavaScript can be used to combine CSS to achieve custom seas.

System-level color selection tools can significantly improve design, development and office efficiency. Its core functions include: 1. Quickly call through global shortcut keys, such as macOS using Shift Command C, while Windows relies on third-party tools and customizes shortcut keys; 2. Supports output of multiple color formats, such as HEX, RGB, HSL, and can be copied into CSS, Swift, Android and other code snippets; 3. Provides magnifying glass function to improve color picking accuracy, and is recommended to use it at the same resolution and appropriate brightness to ensure accuracy. Mastering these methods can greatly save manual conversion time.

SublimeText does not have a built-in "SplitView" button, but split-screen can be manually implemented through layout settings. 1. Click View→Layout and select TwoColumns, ThreeColumns, TwoRows or Grid and other layouts to split the window. 2. Use the default shortcut keys (Windows/Linux: Alt Shift 2 is two columns, Alt Shift 8 is two rows, and macOS uses Option instead of Alt) to quickly switch layouts. 3. Drag the file label to different panes, or right-click to select MovetoGroup, or use File→NewViewintoFile to open in multiple panes

window.onload is a real event, which is triggered when the page and all resources (such as pictures, style sheets, etc.) are fully loaded; 2. document.onload does not exist, and it will not take effect when using it; 3. document.addEventListener('DOMContentLoaded',...) should be used to execute the code after the HTML document is loaded and parsed, without waiting for other resources to load. Therefore, document.onload is a common misunderstanding and does not actually exist and should be avoided.
