Checks if two URLs are on the same origin.
|
|
|
|
- Use `URL.protocol` and `URL.host` to check if both URLs have the same protocol and host.
|
|
|
|
```js
|
|
const isSameOrigin = (origin, destination) =>
|
|
origin.protocol === destination.protocol && origin.host === destination.host;
|
|
```
|
|
|
|
```js
|
|
const origin = new URL('https://www.30secondsofcode.org/about');
|
|
const destination = new URL('https://www.30secondsofcode.org/contact');
|
|
isSameOrigin(origin, destination); // true
|
|
const other = new URL('https://developer.mozilla.org);
|
|
isSameOrigin(origin, other); // false
|
|
```
