Consider:

var playlist = {"bad romance":"gaga", "we cry":"the script"};

How can I get string "gaga" from my code? What is the name of my array in JavaScript programming?

  • That structure is invalid in Javascript if I am not mistaken. You are confusing Dictionaries/Maps with Arrays. Try using '{' instead of '(' and you will have a valid dictionary and can access through playlist['bad romance'] which means playlist[key] – nunofmendes Dec 20 '14 at 13:14

Try Object instead of Array:

var playlist = {"bad romance":"gaga", "we cry":"the script"};
alert(playlist["bad romance"]); //gaga
