.toLowerCase not working properly in condition

My program runs great up until the 3rd question. It does not seem to be functioning properly because the score is not counted if the user inputs any variation of the word 'chinese' with upper or lower case letters, however if I remove the .toLowerCase and user inputs exactly as it states in string - "chinese" the score is counted - so I know that the .toLowerCase is the problem. Let me know if you see anything wrong with this code - focus on the third question because the others run fine. Thank you! 

var continent = prompt("How many continents are there on the planet?");

var score = 0 

if (parseInt(continent) === 7){
  score += 1;
} 

var countries = prompt("How many countries are there on the planet?");

if (parseInt(countries) === 195){
  score += 1;
} 

var language = prompt("What is the most common language?");

if (language.toLowerCase === "chinese") {
  score += 1;
}

document.write ("Your total score is " + score + " out of 3");

I think there is something not right with your syntax. You forgot the end the .toLowerCase with a parenthesis. It should look like this I guess:

language.toLowerCase() === "chinese"

Hi there,

Have you tried having parentheses after the method name? .toLowerCase()
