JavaScript: Capitalize the first letter of each word of a given string
JavaScript Basic: Exercise-50 with Solution
Write a JavaScript program to capitalize the first letter of each word in a given string.
This JavaScript program capitalizes the first letter of each word in a given string. It splits the string into words, capitalizes the first letter of each word, and then joins the words back into a single string.
Visual Presentation:
Sample Solution:
JavaScript Code:
// Define a function named capital_letter with parameter str
function capital_letter(str)
{
// Split the input string into an array of words
str = str.split(" ");
// Iterate through each word in the array
for (var i = 0, x = str.length; i < x; i++) {
// Capitalize the first letter of each word and concatenate it with the rest of the word
str[i] = str[i][0].toUpperCase() + str[i].substr(1);
}
// Join the modified array of words back into a string
return str.join(" ");
}
// Log the result of calling capital_letter with the given string to the console
console.log(capital_letter("Write a JavaScript program to capitalize the first letter of each word of a given string."));
Output:

const capital_letter = (str) => {
// Split the input string into an array of words
str = str.split(" ");
// Iterate through each word in the array
for (let i = 0, x = str.length; i < x; i++) {
// Capitalize the first letter of each word and concatenate it with the rest of the word
str[i] = str[i][0].toUpperCase() + str[i].substr(1);
}
// Join the modified array of words back into a string
return str.join(" ");
};
// Log the result of calling capital_letter with the given string to the console
console.log(capital_letter("Write a JavaScript program to capitalize the first letter of each word of a given string."));
