Hello, I’m so confused! This is what I have done, but I keep getting an error (“expected variable ‘result’ to be defined”)

// Define the ‘makeSandwich()’ function
function makeSandwich(topping1, topping2) {
sandwich = ‘bread’
sandwich =+ sandwich + ‘topping1’
sandwich =+ sandwich + ‘topping2’
sandwich =+ ‘bread’

result = makeSandwich(‘burger patty’, ‘pickles’)
}

Help please! I really wanna master this so I can move on confidently. Thanks!

All compound assignments are written with the operation first, then assignment.

a += 1

which is the equivalent of,

a = a + 1

The addition takes place first, then the assignment.

Note that when using the augmentation operator we do not repeat the variable on the right hand side.

sandwich = bread
sandwich += topping1

Note also that topping1 and topping2 are variables so we would never write them in quotes.
