`base64-js` does basic base64 encoding/decoding in pure JS.

Many browsers already have base64 encoding/decoding functionality, but it is for text data, not all-purpose binary data.

|
|
Sometimes encoding/decoding binary data in the browser is useful, and that is what this module does.

`base64js` has three exposed functions, `byteLength`, `toByteArray` and `fromByteArray`, which both take a single argument.
|
| 25 |
|
|
|
| 26 |
|
|
* `byteLength` - Takes a base64 string and returns length of byte array
|
| 27 |
|
|
* `toByteArray` - Takes a base64 string and returns a byte array
|
| 28 |
|
|
* `fromByteArray` - Takes a byte array and returns a base64 string
