Nesting For Loops [problems with server]

JavaScript

Tell us what’s happening:
Can’t run the test. Click on the run button, and the site
freeze. This bug is existing for one week until now.

Your code so far
for(var i=0;i<arr.length;i++)
for(var j=0;j<arr[i].length;j++)
product*=arr[i][j];


function multiplyAll(arr) {
  var product = 1;
  // Only change code below this line
for(var i=0;i<arr.length;i++)
  for(var j=0;j<arr[i].length;j++)
    arrl[i][j]*product; 
  // Only change code above this line
  return product;
}

// Modify values below to test your code
multiplyAll([[1,2],[3,4],[5,6,7]]);

you have multiple problems in your code. you need curly brackets for code to execute in both for loop .also in nested for loop you have typed arrl instead of arr and also you are not returning or updating product in nested loop.
for loop works like this for(condition){code to execute};

thanks. Just didn’t look at the code.
If the code’s written correctly everything works.
But the problem still exist. If I do some mistake in the code,
tab just freeze and I need to reconnect to the server.
And every topic behaves like that.

Before, just show my mistakes in the output window.
