Junior Developer Central JS Practice Exercise - 21

 

Question: 

Write a Javascript function that returns a passed string with letters in alphabetical order. 

Example String:           'javascript' 

Example Output:          'aacijprstv'

Answer: 

function alphaStr (str) {

return str.split('').sort().join('')

}          

> we declare a function 'alphaStr' 

> it has one parameter 'str' 

> we use the split ('') method on the string 'str' to split all the characters in an array

> we then use the sort() method to sort the characters in alphabetical order

> we then use the join('') method to create a string by concatenating all the sorted elements of the array created 

> we return this line of code to get our alphabetically sorted string
