jQuery is a well-known JavaScript library that helps web developers simplify many tedious operations of JavaScript development. However, not everyone knows that jQuery cannot be used with native JavaScript. This article explains why you can't mix them and how you can avoid this problem.
Why can’t jQuery be used with native JavaScript?
The difference between jQuery and native JavaScript is that it is a JavaScript library. A library is a collection of code that consists of a specific set of functions. This means that when using jQuery, its functionality overrides native JavaScript. That said, if you use both jQuery and native JavaScript in the same application, unexpected behavior may occur and lead to code conflicts.
In addition, jQuery code can operate DOM elements in a simpler and more readable way through the chain programming structure. This is something native JavaScript cannot do. If you use native JavaScript and jQuery, your code may be confusing because the two syntax styles are different. In addition, jQuery also provides many detailed functions, such as event handling functions, etc., which can only be implemented in native JavaScript by writing a lot of code.
How to avoid problems?
The best way is to follow a specific method. This method is to complete a project entirely using native JavaScript or entirely using jQuery. For example, if you choose jQuery as the main framework for your project, you should avoid using native JavaScript entirely. vice versa. This ensures that the code doesn't get cluttered. If you have to use native JavaScript and jQuery, it's better to separate them in your code. This is because you can reduce code conflicts and confusion by separating code, and it can make the code easier to read and maintain.
In addition to following the prescribed methods, you can also follow the following points to ensure the normal operation of the code.
1. Choose different selectors for jQuery and native JavaScript: Try to avoid using the same selector name to avoid code conflicts. This can be done by choosing a different selector, such as using a jQuery-specific selector.
2. Use self-contained code blocks: Self-contained code blocks are a mechanism for encapsulating code. When using self-contained code blocks, you can wrap all of a module's code in a single function. This function returns an object, which ensures that variables and functions in the module do not conflict in the global scope.
3. Use immediate execution function expression: IIFE is a function expression that executes the code in it immediately when it is declared. This is useful because it avoids scope conflicts for variable and function names.
Summary
In web development, although jQuery has many advantages, it cannot be used with native JavaScript. This is because unexpected behavior and code conflicts may occur if they are used simultaneously in the same project. To avoid this problem, you should choose a specific approach and use the same language throughout the project. If you have to use native JavaScript and jQuery, you can ensure that your code behaves properly by separating the code and following a few rules.

Using indexes as keys is acceptable in React, but only if the order of list items is unchanged and not dynamically added or deleted; otherwise, a stable and unique identifier should be used as the keys. 1) It is OK to use index as key in a static list (download menu option). 2) If list items can be reordered, added or deleted, using indexes will lead to state loss and unexpected behavior. 3) Always use the unique ID of the data or the generated identifier (such as UUID) as the key to ensure that React correctly updates the DOM and maintains component status.

The article discusses HTML5 audio formats and cross-browser compatibility. It covers MP3, WAV, OGG, AAC, and WebM, and suggests using multiple sources and fallbacks for broader accessibility.

SVG and Canvas are HTML5 elements for web graphics. SVG, being vector-based, excels in scalability and interactivity, while Canvas, pixel-based, is better for performance-intensive applications like games.

HTML5 enables drag and drop with specific events and attributes, allowing customization but facing browser compatibility issues on older versions and mobile devices.
