“Run the Tests” button isn’t working. On clicking nothing is happening. Tried both in Chrome and Firefox.
Your code so far
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++)
product *= arr[i][j];
// Only change code above this line
return product;
}
// Modify values below to test your code
multiplyAll([[1,2],[3,4],[5,6,7]]);

No, it’s okay to not to have curly braces if there are one statement inside. Anyway, if that’s a syntax error it should show errors in the console, isn’t it?
It was because of the curly braces. Putting them, accepted the answer. May be it’s a bug of freecodecamp. I tried that code without curly braces with my local file and got expected result. Thanks man!
Yeh thats what i read online too, but it seems from my understanding the rule is the statement has to be right after the for/if/else conditions rather then a nested for loop. For testing purposes with the code you have remove one of the for() lines so its not nested and the run button will work.
This is because you have multiple statements. A for loop with only one statement works without braces, but will fail if it has multiple.
The best way to tell without a linter if you can omit the braces, is that they must be single line. The same is true for if statements.
// does not work, multiple statements
for(var i = 0; i < arr.length; i++)
for(var j = 0; j < arr[i].length; j++)
product *= arr[i][j];
if (true)
if (somethingElse)
// does work, braces for multiple statements, none for the single line one
for(var i = 0; i < arr.length; i++) {
for(var j = 0; j < arr[i].length; j++) product *= arr[i][j];
}
if (true) return 'yay'
First I tried with browser console. Worked perfect:
Then I tried with normal writing scripts inside HTML file. No problem either:
Output in the console of the above code:
So, it’s okay to have no curly braces till all nested loops or if-else statements has one statement.
Here, the first for has only one for loop and the second one has only one statement.
