yarn add pretty-class
Usage
Importing the Package
import prettyClass from 'pretty-class';
Function Signature
export type prettyClassTypes = string | Record<string, boolean> | prettyClassTypes[] | undefined | null | false; const prettyClass: (...args: prettyClassTypes[]) => string;

Returns
- A string containing the concatenated class names.
Example Usage
Basic String Input
const result = prettyClass('class1', 'class2');
console.log(result); // Output: "class1 class2"
Conditional Classes
const result = prettyClass({ 'class1': true, 'class2': false, 'class3': true });
console.log(result); // Output: "class1 class3"
Nested Arrays
const result = prettyClass(['class1', { 'class2': true }, ['class3', { 'class4': false }]]);
console.log(result); // Output: "class1 class2 class3"
Mixed Inputs
const result = prettyClass('class1', { 'class2': true }, ['class3', null, false]);
console.log(result); // Output: "class1 class2 class3"
Benefits
- Lightweight: Minimal code footprint.
- Flexible: Supports various input types.
- Recursive: Handles nested arrays gracefully.
- Typed: Fully typed for TypeScript users.

How to work with dates and times in js?
Jul 01, 2025 am 01:27 AM
The following points should be noted when processing dates and time in JavaScript: 1. There are many ways to create Date objects. It is recommended to use ISO format strings to ensure compatibility; 2. Get and set time information can be obtained and set methods, and note that the month starts from 0; 3. Manually formatting dates requires strings, and third-party libraries can also be used; 4. It is recommended to use libraries that support time zones, such as Luxon. Mastering these key points can effectively avoid common mistakes.

What is event bubbling and capturing in the DOM?
Jul 02, 2025 am 01:19 AM
Event capture and bubble are two stages of event propagation in DOM. Capture is from the top layer to the target element, and bubble is from the target element to the top layer. 1. Event capture is implemented by setting the useCapture parameter of addEventListener to true; 2. Event bubble is the default behavior, useCapture is set to false or omitted; 3. Event propagation can be used to prevent event propagation; 4. Event bubbling supports event delegation to improve dynamic content processing efficiency; 5. Capture can be used to intercept events in advance, such as logging or error processing. Understanding these two phases helps to accurately control the timing and how JavaScript responds to user operations.
