--description--

Your loop now needs a proper iterator. The iterator is a variable you can declare specifically in your for loop to control how the loop iterates or goes through your logic.

It is a common convention to use i as your iterator variable in a loop. A for loop allows you to declare this in the parentheses (). For example, here is a for loop that declares an index variable and assigns it the value 100.

for (let index = 100; "second"; "third") {

}

Replace the string "iterator" with a let declaration for the variable i. Assign it the value 0 to start. This will give the i variable the value 0 the first time your loop runs.

--hints--

You should use let to declare an i variable.

assert.match(__helpers.removeJSComments(code), /let\s+i/);

You should assign 0 to your i variable.

assert.match(__helpers.removeJSComments(code), /let\s+i\s*=\s*0/);

Your for loop should start an i iterator at 0.

assert.match(__helpers.removeJSComments(code), /for\s*\(\s*let\s+i\s*=\s*0/);
