i have a script that creates an array of words from a sencence and then capitalises each letter i am getting sintax errors whenever i run the script. Here is all of the JavaScript that is related to the input and output boxes.
function validateForm() { var addressInput = regForm.addressBox.value; var postCode = regForm.postCode.value; var townInput = regForm.townBox.value; var addressArray = addressInput.split(" "); var townArray = townInput.split(" "); for (let i = 0; i < addressArray.length; i++) { var addressArray[i] = addressArray[i][0].toUpperCase() + addressArray[i].substring(1); } var addressCap = addressArray.join(" "); for (let i = 0; i < townArray.length; i++) { var townArray[i] = townArray[i][0].toUpperCase() + townArray[i].substring(1); } var townCap = townArray.join(" "); if (addressCap > 1 ) { if (townCap > 1) { if (postCode == 4) { document.getElementById('addressOutput').innerHTML = "Your address is: " + addressCap + ", " + townInput + ", " + postCode; } if (postCode != 4) { document.getElementById('addressOutput').innerHTML = "Please fill out the post code box"; } } if (townCap < 1) { document.getElementById('addressOutput').innerHTML = "Please fill out the town box"; } } if (addressCap < 1) { document.getElementById('addressOutput').innerHTML = "Please check your address for errors"; } }
the error is for the i
in addressArray[i]
and the townArray[i]
i feel like it is stupidly simple but im stumped.

Answer
var addressArray[i] =
isn’t valid syntax.
Drop the var
, as you’re not declaring a variable:
addressArray[i] = addressArray[i][0].toUpperCase() + addressArray[i].substring(1);
