## Function min(a, b)

importance: 1

Write a function `min(a,b)`

which returns the least of two numbers `a`

and `b`

.

For instance:

```
min(2, 5) == 2
min(3, -1) == -1
min(1, 1) == 1
```

A solution using `if`

:

```
function min(a, b) {
if (a < b) {
return a;
} else {
return b;
}
}
```

A solution with a question mark operator `'?'`

:

```
function min(a, b) {
return a < b ? a : b;
}
```

P.S. In the case of an equality `a == b`

it does not matter what to return.
