Recursive multiplication in array - JavaScript
We are required to write a JavaScript function that takes in an array of nested arrays of Numbers and some false values (including 0) and some strings as wel. the function should return the product of number values present in the nested array.
If the array contains some 0s, we should ignore them as well. Let’s write the code for this function −
Example
const arr = [1, 5, 2, null, [
2, 5, null, undefined, false, 5, [
1, 3, false, 0, 2
], 4, 2, false
], 4, 6, 0
];
const recursiveMultiplication = arr => {
let prod = 1;
for(let i = 0; i < arr.length; i++){
if(Array.isArray(arr[i])){
prod *= recursiveMultiplication(arr[i]);
}else{
prod *= arr[i] || 1;
};
};
return prod;
};
console.log(recursiveMultiplication(arr));Output
Following is the output in the console −
