Question regarding the "Reviewing JavaScript Variables Quiz".

I'm confused as to this question on the quiz:

Complete the code below to store the value 100 in the variable name score 

var score =

From this example, how are we supposed to know what type of JavaScript value to input? Numbers, Strings, Booleans, etc.

Hi Jorge,

The good thing about JavaScript it's smart. It distiguieshes if a input for the variable a string ( 'this is a string') or an Integer ( 123 ).

But word of advice : if the challange says you have to input 100 then you have to put in a number -> if it said '100' then you have to put in '100' (which is a string).

A score would be a number data type because it would need to be able to be manipulated using math operations.

var score = 100;
