# --description--
Starting in the top left corner of a 2×2 grid, and only being able to move to the right and down, there are exactly 6 routes to the bottom right corner.
Iniziando nell'angolo in alto a sinistra di una griglia 2x2, e avendo l'abilità di muoversi solo verso destra e verso il basso, ci sono esattamente 6 strade verso l'angolo in basso a sinistra.
<img class="img-responsive center-block" alt="a diagram of 6 2 by 2 grids showing all the routes to the bottom right corner" src="https://cdn-media-1.freecodecamp.org/project-euler/1Atixoj.gif" style="background-color: white; padding: 10px;" />

How many such routes are there through a given `gridSize`?
Quante strade di questo tipo ci sono data la dimensione della griglia `gridSize`?

`latticePaths(4)` should return a number.
`latticePaths(4)` dovrebbe restituire un numero.
```js
assert(typeof latticePaths(4) === 'number');
```
`latticePaths(4)` should return 70.
`latticePaths(4)` dovrebbe restituire 70.
```js
assert.strictEqual(latticePaths(4), 70);
```
`latticePaths(9)` should return 48620.
`latticePaths(9)` dovrebbe restituire 48620.
```js
assert.strictEqual(latticePaths(9), 48620);
```
`latticePaths(20)` should return 137846528820.
`latticePaths(20)` dovrebbe restituire 137846528820.
```js
assert.strictEqual(latticePaths(20), 137846528820);
