JWT

JSON Web Token

A compact, URL-safe token format for securely transmitting claims between parties.

Technical Detail

JWT is part of the web platform's core infrastructure. Modern browsers implement compact 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 jwt correctly, avoid common pitfalls, and optimize for performance and security.

Example

```javascript
// JWT: web API example
const response = await fetch('/api/resource');
const data = await response.json();
console.log(data);
```
