//This is my Problem Complete the getLetter(s) function in the editor. It has one parameter: a string, , consisting of lowercase English alphabetic letters (i.e., a through z). It must return A, B, C, or D depending on the following criteria:
If the first character in string is in the set {aeiou}, then return A.
If the first character in string is in the set {bcdfg}, then return B.
If the first character in string is in the set {hjklm},, then return C.
If the first character in string is in the set {npqrstvwxyz}, then return D.
I am trying to implement the above scenarion and to dthis I have written the following code.
//Here is my code
function getLetter(s) {
let letter;
// Write your code here
switch (s) {
case s.match(/[aeiou]/g).includes(s[0]):
letter = 'A'
break;
case s.match(/[bcdfg]/g).includes(s[0]):
letter = 'B'
break;
case s.match(/[hjklm]/g).includes(s[0]):
letter = 'C';
break;
case s.match(/[npqrstvwxyz]/g).includes(s[0]):
letter = 'D';
break;
default:
console.log("hello")
}
return letter
}
The code is showing error. Would any help me to figure it out? How can I implement the above task using switch statement.
I don't know that much switch case, but maybe you can use parenthesis for the switch statement and if "s.match(/[aeiou]/g).includes(s[0])" return true or false And you forgot ";" after the two first assignment
the way you wrote the switch case may be partially correct in GoLang. but in Javascript, it is not possible to achieve this using Switch-Case statement.
Better try using if-else-if statement something like below
if(s.test(/^[aeiou]/)) {
return 'A';
} else if(s.test(/^[bcdfg]/)) {
return 'B'
}
Check out this: Switch statement for string matching in JavaScript. The issue is that match returns null, which breaks the switch statement. Use
switch(s){
case str.match(/^xyz/)?.input:
//code
break;
This stops the match from returning null.
