how can i create a constant named "title" and assigned to a string named "A dance with the dragon" ?

it´s easier then it looks ;-)

let title = "A dance with the dragon"

first you set WHAT it is... "let" is a constant value, NOT changeable once it´s been defined. "var" is a variable and can be changed and modified as many times as you like.

so we start with a let since we want a constant. now title... in programming (any language) it´s best practice to use something called "camelCasing" (you can see it hu? :-))

means the name of a variable, constant, function,... STARTS with lowercase and then continues every word upper case..

Title of movie would be "titleOfMovie"

so

let title = "A dance with the dragon"

We want that the constant "title" EQUALS "A dance with the dragon" so we write it that way ;-)
