--description--

Remember in your previous loop that you used the addition operator + to increase the value of i by 1.

You can do a similar thing with a string value, by appending a new string to an existing string. For example, hello = hello + " World"; would add the string " World" to the existing string stored in the hello variable. This is called concatenation.

In your for...of loop, use the addition operator to concatenate the row value to the result value.

--hints--

You should use the concatenation operator on your result variable.

assert.match(__helpers.removeJSComments(code), /(?:result\s*\+|\+\s*result)/);

You should concatenate row to your result variable.

assert.match(__helpers.removeJSComments(code), /result\s*\+\s*row|row\s*\+\s*result/);

You should assign the result of your concatenation back to the result variable.

assert.match(__helpers.removeJSComments(code), /result\s*=\s*(result\s*\+\s*row|row\s*\+\s*result);?/);

  rows.push(i);
