## 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;
```
