On Rock, Paper, Scissors task, exercise 5,

Create a new function named `getComputerChoice`

with no parameters. Inside its block, utilize `Math.random()`

and `Math.floor()`

to get a whole number between 0 and 2. Then, depending on the number, `return`

either `'rock'`

, `'paper'`

, or `'scissors'`

.

so I wrote this code:

```
function getComputerChoice() {
const randomNumber = Math.floor(Math.random()*3);
switch (randomNumber) {
case 0:
return 'rock';
case 1:
return 'paper';
case 2:
return : 'scisscors';
};
}
```

I got error. The project walkthrough shows that he used function expression not this âfunction declarationâ but I donât understand why this is wrong?
