Certainly! You can achieve this by splitting the input string into words, capitalizing each word, and then joining them back into a new string. Here's a simple JavaScript program for this:

function capitalizeWords(inputString) {
  // Split the input string into an array of words
  const words = inputString.split(' ');

  // Capitalize each word
  const capitalizedWords = words.map(word => {
    // Ensure the word is not an empty string
    if (word.length > 0) {
      return word.charAt(0).toUpperCase() + word.slice(1);
    } else {
      return '';
    }
  });

  // Join the capitalized words into a new string
  const resultString = capitalizedWords.join(' ');

  return resultString;
}

// Example usage:
const inputString = 'hello world! this is a test.';
const result = capitalizeWords(inputString);

console.log(result); // Outputs: 'Hello World! This Is A Test.'

This capitalizeWords function takes an input string, splits it into an array of words, capitalizes each word, and then joins them back into a new string. The example usage demonstrates how to use the function with a sample input string.
