Tell us what’s happening:

My loop running a condition to check each array item that is typeof = “string” checking if it isNaN to return it as-is, as a string, else converts the number into a number results in an array that replaces all strings to NaN.

Your code so far

function frankenSplice(arr1,arr2,index) {
let newArr = arr2.slice(0);
let tempArr = arr1.slice(0);
newArr.splice(index, 0, tempArr);
const arrayFromString = String(newArr).split(',');
let resultArr =[];

for (let i =0; i < arrayFromString.length; i++) {
if (isNaN(Number(arrayFromString[i])) === "true") {resultArr[i]  = arrayFromString[i];
}
else {resultArr[i]  = Number(arrayFromString[i]);}
}
return resultArr;
}

console.log(frankenSplice([1, 2], ["a", "b"], 1))

Welcome to the forum @userNameIsTooShort

isNaN checks if the argument is not a number.

If the argument is not a number then it evaluates to true.

If the argument is a number, then it evaluates to false.

Happy coding
