In this Article we will go through how to round a number to the nearest multiple of a given value only using single line of code in JavaScript.
This is a one-line JavaScript code snippet that uses one of the most popular ES6 features => `Arrow Function`

.

Let's define this short function:

```
const roundNearest = (value, nearest) => Math.round(value / nearest) * nearest;
```

```
roundNearest(100, 30); // 90
roundNearest(200, 30); // 210
roundNearest(200, 40); // 200
```
