I already found out how to count words in a given string, but I’m not sure why my previous code is wrong (albeit it’s much longer than it needs be). Here’s my code:
function countWords(str) {
totalSpaces = 0
for (var i = 0; i < str.length; i++) {
if (str[i] === " ") { // if str[i] is a space, add 1 to totalSpaces
totalSpaces += 1
} else {
return 'No spaces!'
}
}
return totalSpaces
}
