Interview Question (easy).js

// You receive the name of a city as a string, and you need to return a string that shows how many times each letter shows up in the string by using asterisks (*).

// For example:
// As you can see, the letter c is shown only once, but with 2 asterisks.
// The return string should include only the letters (not the dashes, spaces, apostrophes, etc). There should be no spaces in the output, and the different letters are separated by a comma (,) as seen in the example above.
// Note that the return string must list the letters in order of their first appearance in the original string.

// More examples:

// "Bangkok"    -->  "b:*,a:*,n:*,g:*,k:**,o:*"

//P: string
//R: return a string that shows how many times each letter shows up in the string by using asterisks (*). The return string should include only the letters (not the dashes, spaces, apostrophes, etc). There should be no spaces in the output, and the different letters are separated by a comma (,) the return string must list the letters in order of their first appearance in the original string.
//E: "Bangkok"    -->  "b:*,a:*,n:*,g:*,k:**,o:*"
//P:

    let city1 = city.toLowerCase().split(' ').join('');
