Feedback on my simple solution, however it took me forever to come up with it.

/* Ask at least five questions

Keep track of the number of questions the user answered correctly

Provide a final message after the quiz letting the user know the number of questions he or she got right.

Rank the player. If the player answered all five correctly, give that player the gold crown: 3-4 is a silver crown; 1-2 correct answers is a bronze crown and 0 correct is no crown at all.

*/

var count = 0;
var country = prompt("Are you in the US?");
if(country === 'yes') {
  count++;
}
var hasDog = prompt("Do you have a dog?");
if(hasDog === 'yes') {
  count++;
}
var likesRock = prompt("Do you like rock music");
if(likesRock === 'yes') {
  count++;
}
var knowsJavascript = prompt("Do you know javascript");
if(knowsJavascript === 'yes') {
  count++;
}
var whoIs = prompt("Are you Nelson");
if(whoIs === 'yes') {
  count++;
}

if(count === 5) {
  alert('Gold Crown');
} 
else if(count <= 4 && count >= 3) {
  alert('silver crown');
}
else if(count <= 2 && count >= 1) {
  alert('Bronze crown');
}
else {
  alert('no crown');
}

To preserve the appearance of your code, use Markdown formatting. There's a video about it.

I would like to point out if the users types Yes they won't be awarded the point because of the strict comparison Yes is not equal to yes.

So you should convert their input to lower case.

Steven Parker thanks for pointing that out. I have fixed it. @ Carl Evison thank you for your feedback too. Will make it more flexible.

I often take Carl's suggestion one step further and allow anything that starts with "y" (like "Yes", "yo", "yup", etc.) to be taken as an affirmative response:

var ask = question => prompt(question).toLowerCase().startsWith("y");
// then later...
if (ask("Do you know JavaScript? ")) {
