How to add character before each word in a string

You could write a function like this:

function addCharacterBeforeEachWord(str, char) {
// Split the string into an array of words
const words = str.split(' ');

// Loop through the array of words
for (let i = 0; i < words.length; i++) {
// Add the character before each word
words[i] = char + words[i];
}

// Join the array of words back into a single string
return words.join(' ');
}

Then just call the function:

const modifiedString = addCharacterBeforeEachWord('Hello World', '*');
console.log(modifiedString); // Output: "*Hello *World"
