This is my code, I can't find the bug.

What ends up happening is that all the questions are pushed to the correct_answer array as if they were answered correctly even if they were not. Can anyone see where the bug is?

These are the arrays needed to store the user answers as 
correct and incorrect, and there is the array to store 
the questions and correct answers.

var user_answer;
var correct_answer = [ ];
var incorrect_answer = [ ];
var questions_answers = [
  ["How many continents are there?", "7"],
  ["What is the capital of France?", "Paris"],
  ["Who is the president of the USA?", "Donald Trump"]

// This function prints an array as a numbered list

function printList( list ) {
  var listHTML = '<ol>';
  for (var i = 0; i < list.length; i += 1) {
    listHTML += '<li>' + list[i] + '</li>';
  listHTML += '</ol>';

// Replaces document.write

function print(message) {

/*This is the loop that asks and checks the questions, 
this is what isn't working

for (var i = 0; i < 3; i +=1) {
  user_answer = prompt(questions_answers[i][0]);
  if ( user_answer.toLowerCase === questions_answers[i][1].toLowerCase ) {
   correct_answer.push( questions_answers[i][0] );
  } else {
   incorrect_answer.push( questions_answers[i][0] );

// What will show after the user answers

print("<h2>You got these questions right!</h2>");
printList( correct_answer );
print("<h2>You got these questions wrong.</h2>");
printList( incorrect_answer );

one thing i notice is that you are not properly calling toLowerCase. it is a method and must be followed by parens (), so myString.toLowerCase().
