Question
My question: I don't understand why the last output has two letters inside. Can you please fix my code?
Write a function `mostFrequentLetter(string)` that takes a
string as an argument and returns the character that appears the
most often. In case of a tie, you may return any of the characters.
The string will have at least one character.
Examples:
console.log(mostFrequentLetter("apple")); // "p"
console.log(mostFrequentLetter("banana")); // "a"
console.log(mostFrequentLetter("What about a longer string?")); // " "
My code:
function countChar(string) {
letcountChar = {};
for (leti = 0; i < string.length; i++) {
letchar = string[i];//the future key elements
if (charincountChar){//create keys
countChar[char]++;//create values
}else {
countChar[char] = 1;//create values
}
}
returncountChar;
}
function mostFrequentLetter(string) {
letmaxCount = countChar(string);
letnewArr = Object.entries(maxCount);
letmax = newArr[0][1];
letresult = [];
for (leti = 0; i < newArr.length; i ++){
letelChar = newArr[i][0]
letelNum = newArr[i][1];
if (elNum > max){
max = elNum;
result.push(elChar);
}
}
return result.join();
}
console.log(mostFrequentLetter("apple"));
console.log(mostFrequentLetter("banana"));
console.log(mostFrequentLetter("What about a longer string?"))
My out put:
"p"
"a"
"a", " "
