Hi Oussama, pretty much everything in Javascript is an object, hence the name of object oriented programming language.

Arrays use and numerical index whereas objects use key value pairs.

Yes! an object basically means that it has properties and methods! If you look at an array, it does indeed have properties like .length, and also methods like .concat, .join, etc... Properties tell something about the object, and methods do something to the object! JS is object-oritented! Hope this helps :)
