Debugging: Catch Unclosed Parentheses, Brackets, Braces and Quotes problem

JavaScript
1 
let myArray = [1, 2, 3];
let arraySum = myArray.reduce((previous, current =>  previous + current));
console.log(`Sum of array values is: ${arraySum}`);

I get error: Your code should fix the missing piece of the

.reduce()

method. The console output should show that “Sum of array values is: 6”.

Any ideas?

an hint: if I put this in the browser console this error comes up:

VM58:2 Uncaught ReferenceError: previous is not defined

so you probably needs to look around there for your issue. Maybe check what is the syntax for reduce()
