We have this task:

You are given a variable `celsius`

representing a temperature in Celsius. Use the variable `fahrenheit`

already defined and assign it the Fahrenheit temperature equivalent to the given Celsius temperature. Use the formula mentioned above to help convert the Celsius temperature to Fahrenheit.

I solved it with this:

```
function convertToF(celsius) {
let fahrenheit = celsius * 9 / 5 + 32;
return fahrenheit;
}
convertToF(30);
```

But I guess, if we are tlaking in general, I could code similar function without any variables(like below)? What’s the best practice?

```
function convertToF(celsius) {
return celsius * 9 / 5 + 32;
}
convertToF(30);
```
