Hey! It seems like I’m having trouble understanding what you’re trying to achieve. Could you provide an example of what you’re attempting to do and maybe share the error message you’re encountering?

Most JavaScript statements look like this:

statement (condition) {
	code
}

The if statement is no different:

if (condition) {
	// code
}

You can then chain as many else if statements as you want:

if (condition1) {
	// code1
} else if (condition2) {
	// code2
}

Note that the else if means this condition will only be checked if the previous condition evaluated to false.

At the end of this chain, you can use an else statement to cover any other conditions:

if (condition1) {
	// code1
} else if (condition2) {
	// code2
} else {
	// code3
}

It might help your understanding to see this in plain english:

if condition 1 is true, then
	do code 1
otherwise, if condition 2 is true, then
	do code 2
lastly, if none of the above were true, then
	 do code 3
