Array's Items Using For Loops

JavaScript
1

Tell us what’s happening:
function filteredArray(arr, elem) {

let newArr = ;

// Only change code below this line

for (let i = 0; i < arr.length; i++) {

if (arr[i] >=3) {

newArr.push(arr[i]);

}

}

// Only change code above this line

return newArr;

}

console.log(filteredArray([[3, 2, 3], [1, 6, 3], [3, 13, 26], [19, 3, 9]], 3));

Your code so far


function filteredArray(arr, elem) {
let newArr = [];
// Only change code below this line
for (let i = 0; i < arr.length; i++) {
if (arr[i] >=3) {
  newArr.push(arr[i]);
}
} 
// Only change code above this line
return newArr;
}

console.log(filteredArray([[3, 2, 3], [1, 6, 3], [3, 13, 26], [19, 3, 9]], 3));

Tell us what’s happening. What is your question? With what exactly you need help with?

3

Looks like you’ve made the incorrect assumption that the length of the subarrays of arr will always be three.

4

do you understand what this challenge requires? you never use the elem parameter

Hi @shakib

Since this is a nested array, you should be using two For Loops and use elem to check the nested array. Later you can push the result to a new array using the temp variable.

I hope this procedure helps!
