Add three properties to this object: population with a value of 2.211e6 (that's 2.211 million using exponential notation

Add three properties to this object: population with a value of 2.211e6 (that's 2.211 million using exponential notation), a latitude property with a value of '48.8567 N', and a longitude property with a value of '2.3508 E'.

I can't find my mistake It keeps writing that there is no 3 properties 'population, 'latitude' and etc.

script.js
var paris = { population: 2.211e6, latitude: 48.8567 N, longtitude: '2.3508 E'
};

Hey there! What's tripping you is a simple typo :)

It should be "longitude", not "longtitude". Also the latitude statement should be in " " since it has a letter in the end (48.8567 N) which needs to be included, making it a string, not a number.

Good luck!
