Serializes a cookie name-value pair into a Set-Cookie header string.
|
|
|
|
- Use template literals and `encodeURIComponent()` to create the appropriate string.
|
|
|
|
```js
|
|
const serializeCookie = (name, val) =>
|
|
`${encodeURIComponent(name)}=${encodeURIComponent(val)}`;
|
|
```
|
|
|
|
```js
|
|
serializeCookie('foo', 'bar'); // 'foo=bar'
|
|
```
