I'm having trouble identifying the bug in this code as it's not generating any output:
function convertToTitleCase (inputString) {
var wordArray = inputString.split(' ');
var outputArray = [];
for (var j = 0; j < wordArray.length; j++) {
outputArray.push(wordArray[j].charAt(0).toUpperCase() + wordArray[j].slice(1));
};
return outputArray.join(' ');
}
alert(convertToTitleCase("the quick brown fox"));
In my opinion, changing arr[x] to arr[i] would be more appropriate.
function reverseWords(str) {
var arr = str.split(' ');
var reversed = [];
for (var i = 0; i < arr.length; i++) {
reversed.push(arr[i].split('').reverse().join(''));
};
return reversed.join(' ');
}
alert(reverseWords("hello world"));Concise solution in a single line:
let sentence = "the quick brown fox",
capitalizedWords = sentence.split(" ").map(w => w[0].toUpperCase() + w.slice(1)).join(" ");
console.log(capitalizedWords); // "The Quick Brown Fox"
