Rock, paper scissors project

I am stuck on step 3 of the project. I have written this code:

const getUserChoice = userInput => {
userInput = userInput.toLowerCase();
if (userInput === ‘rock’ || userInput === ‘paper’ || ‘scissor’) {
return userInput;
} else {

And I keep getting this error:

SyntaxError: Unexpected token )
at createScript (vm.js:53:10)

at run (bootstrap_node.js:427:7)
at startup (bootstrap_node.js:151:9)

Can someone help me understand what I need to fix?

Thank you,

I think the if-statement condition has a mistake:

if (userInput === 'rock' || userInput === 'paper' || 'scissor') {

should be

if (userInput === 'rock' || userInput === 'paper' || userInput === 'scissor') {

because just having
|| 'scissor'
would work the same as always doing
|| true
(since non-empty strings work the same way as true (they’re truthy) when you’re doing an if-statement’s condition.

I don’t see a line that has }); in the code above.
But the } needed to finish the function isn’t written in the code above.

Thank you so much for your help.
