Find the total occurrences of an element in a JavaScript multidimensional array
Advertisements
Given a multidimensional array in JavaScript, we need to find the count of occurrences of an element in the array.
var words = [
["one", "two", "three"],
["nine", "one", "four"],
["six", "two", "eight"],
["seven", "five", "ten"],
];
const calculateCount = (arr, query) => {
let count = 0;
for(let i = 0; i < arr.length; i++){
if(arr[i] === query){
count++;
continue;
};
if(Array.isArray(arr[i])){
count += calculateCount(arr[i], query);
}
};
return count;
};
console.log(calculateCount(words, "two")); //2
