You can declare the variable with no value assignment.

var answer;

Creates a variable named answer but stops short of assigning a value.

Your method of declaring a variable is incorrect.

a variable is declared by simply writing the following:

var myRandomVariableNameCoolStuffBro;

variables can be instantiated without any initial value given, and later be passed a value.

myRandomVariableNameCoolStuffBro = 5;
myRandomVariableNameCoolStuffBro = 'now I am a string!';

if you want to declare a variable and pass it a value immediately, 

var myRandomVariableNameCoolStuffBro = 'this value is of type string and instantly assigned to the variable';
