Caso de título Una oración
function titleCase(str) {
const newTitle = str.split(" ");
const updatedTitle = [];
for (let st in newTitle) {
updatedTitle[st] = newTitle[st][0].toUpperCase() + newTitle[st].slice(1).toLowerCase();
}
return updatedTitle.join(" ");
}
titleCase("I'm a little tea pot");
console.log(titleCase("I'm a little tea pot"))
console.log(titleCase("HERE IS MY HANDLE HERE IS MY SPOUT"))
console.log(titleCase("sHoRt AnD sToUt"));
/*Code Explanation
Split the string by white spaces, and create a variable to track the updated title.
Then we use a loop to turn turn the first character of the word to uppercase
and the rest to lowercase. by creating concatenated string composed of the whole word
in lowercase with the first character replaced by its uppercase. */
// Regex
function titleCase(str) {
return str
.toLowerCase()
.replace(/(^|\s)\S/g, L => L.toUpperCase());
}
/* Code Explanation
The solution works by first lowercasing all the characters in the string and then only uppercasing the first character of each word.
* Lowercase the whole string using str.toLowerCase().
* Replace every word’ first character to uppercase using .replace.
* Search for character at the beginning of each word i.e. matching any
character following a space or matching the first character of the
whole string, by using the following pattern.
* Regex explanation:
* Find all non-whitespace characters (\S)
* At the beginning of string (^)
* Or after any whitespace character (\s)
- The g modifier searches for other such word pattern in the
whole string and replaces them.
- This solution works with national symbols and accented letters
as illustrated by following examples
international characters:
‘бабушка курит трубку’ // → ‘Бабушка Курит Трубку’
accented characters:
‘località àtilacol’ // → ‘Località Àtilacol’
