Sample Solution:
JavaScript Code:
// Function to alphabetize a string
function alphabetize_string(str)
{
// Split the string into an array of characters, sort them alphabetically, then join them back into a string
return str.split('').sort().join('').trim();
}
// Output the result of alphabetizing the string 'United States'
console.log(alphabetize_string('United States'));

SUadeeinsttt
Explanation:
The above JavaScript code defines a function called "alphabetize_string()" that takes a string ('str') as input and returns the string with its characters sorted alphabetically. Here's a breakdown of what each part does:
- str.split(''): Splits the input string into an array of characters.
- .sort(): Sorts the array of characters alphabetically.
- .join(''): Joins the sorted array back into a string.
- .trim(): Removes any leading or trailing whitespace from the resulting string.
- return: Returns the alphabetized string.
