Decodes a string of data which has been encoded using base-64 encoding.
|
|
|
|
- Create a `Buffer` for the given string with base-64 encoding.
|
|
- Use `Buffer.prototype.toString()` to return the decoded string.
|
|
|
|
```js
|
|
const atob = str => Buffer.from(str, 'base64').toString('binary');
|
|
```
|
|
|
|
```js
|
|
atob('Zm9vYmFy'); // 'foobar'
|
|
```
