Use switch case function getLetter(s) { let first = s[0]; let letter; switch (true) { case "aeiou".includes(first): letter = 'A'; break; case "bcdfg".includes(first): letter = 'B'; break; case "hjklm".includes(first): letter = 'C'; break; default: letter = 'D'; } return letter; }

` DON'T use switch case

function getLetter(s) {
    let letter;
    // Write your code here
    let setchars =[
        {key: 'A', value:"aeiou"},
        {key: 'B', value:"bcdfg"},
        {key: 'C', value:"hjklm"},
    ]
    
for(const {key,value} of setchars){
    if(value.includes(s[0])) return key; 
}
 return 'D'   
}
