### Make Math Global

Object.getOwnPropertyNames(Math).forEach(i => window[i] = Math[i]);

`// or with map, just to be shorter`

Object.getOwnPropertyNames(Math).map(i => window[i] = Math[i]);

`// if this points to window`

Object.getOwnPropertyNames(Math).map(i => this[i] = Math[i]);

`// or using the deprecated "with" statement`

with (Math) {

console.log(PI, E, SQRT2, cos(1));

`}`

While not very useful, I sometimes like to make the entire `Math`

object global on the window – just when speed coding and playing around.
