 ### Round number to n digits

-Correctly rounds a number to the specified number of digits.
+Use `Math.round()` and template literals to round the number to the specified number of digits.
+Omit the second argument, `decimals` to round to an integer.

 ```js
-const round = (n, decimals = 0) =>
-  Number(`${Math.round(`${n}e${decimals}`)}e-${decimals}`)
+const round = (n, decimals=0) => Number(`${Math.round(`${n}e${decimals}`)}e-${decimals}`);
 // round(1.005, 2) -> 1.01
 ```
