How to use forEach and String Manipulation In Javascript
Using forEach loop and string manipulation to capitalize the first letter of every sentence involves splitting the string into an array of sentences, iterating over each sentence with forEach, and capitalizing the first letter before joining the array back into a string.
Example:
function capitalizeSentences(str) {
const sentences = str.split('. ');
sentences.forEach((sentence, index) => {
sentences[index] = sentence.charAt(0).toUpperCase() + sentence.slice(1);
});
return sentences.join('. ');
}
const inputString = "hello. how are you? i am fine.";
const capitalizedString = capitalizeSentences(inputString);
console.log(capitalizedString);
Output
Hello. How are you? i am fine.
