Regex
Regular Expression
A sequence of characters defining a search pattern, used for string matching and text manipulation.
Technical Detail
Regex is part of the web platform's core infrastructure. Modern browsers implement sequence through standardized Web APIs, ensuring consistent behavior across Chrome, Firefox, Safari, and Edge. The relevant specifications are maintained by the W3C, WHATWG, or IETF. Understanding the underlying protocol or mechanism helps developers use regex correctly, avoid common pitfalls, and optimize for performance and security.
Example
```javascript
// Regex: web API example
const response = await fetch('/api/resource');
const data = await response.json();
console.log(data);
```
