Returns the length of a string in bytes.

Convert a given string to a [`Blob` Object](https://developer.mozilla.org/en-US/docs/Web/API/Blob) and find its `size`.
|
|
|
|
```js
|
|
const byteSize = str => new Blob([str]).size;
|
|
```
|
|
|
|
```js
|
|
byteSize('😀'); // 4
|
|
byteSize('Hello World'); // 11
|
|
``` |
