{# canonical_base is the OWNING tenant's origin: all 16 Peasy domains serve the same catalogue, so a page rendered by a non-owner points its canonical at the owner instead of competing with it. Falls back to this site for static/self-owned pages. #}

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);
```
