Learn Form Validation by Building a Calorie Counter - Step 22

Tell us what’s happening:

I don’t think I am suppose to use const strArray as the variable.

Your code so far

for (let i = 0; i < strArray.length; i++) {
const strArray = ![“+”, “-”, " "].includes()
}
}

Well, seeing as you already declared strArray in the first line of the function, I think that is a good observation :slightly_smiling_face:

The instructions are
Your for loop should use !["+", "-", " "].includes() .

How do I use it correctly?

for (let i = 0; i < strArray.length; i++) {
const cleanStrArray = ![“+”, “-”, " "].includes()
}
}

Do i need to use a if statement?

Do you really want to declare cleanStrArray with const inside the for loop. You already declared it before the for loop. What happens if you declare it again inside of the for loop?

“You will need to check if the array ["+", "-", " "] does not include the current character.”

This sounds like you will need to use an if statement, doesn’t it?

“If it is not, push it to the cleanStrArray.”

This sentence is telling you to use the push method on the array.
