## Informative

- Commonly used in mathematics, physics and robotics.

- [Infix notation](http://en.wikipedia.org/wiki/Infix_notation) is more succinct than function notation, which makes it more preferable

#### Prior Art

- Python

  - `math.pow(x, y)`

  - `x ** y`

- CoffeeScript

  - `x ** y`

- F#

  - `x ** y`

- Ruby

  - `x ** y`

- Perl

  - `x ** y`

- Lua, Basic, MATLAB, etc.

  - `x ^ y`

#### Usage

```js

// x ** y

let squared = 2 ** 2;

// same as: 2 * 2

let cubed = 2 ** 3;

// same as: 2 * 2 * 2

```

```js

// x **= y

let a = 2;

a **= 2;

// same as: a = a * a;

let b = 3;

b **= 3;

// same as: b = b * b * b;

```
