array map in javascript

Hi, im not sure of this one. I want to have a map in javascript. or does it already exist.

i have an array of STR1:STR2
i must access the array using STR1 and find STR2 in that array.
so thats a map<string, map<string, string>>.

thanks. i have no clu on this one

Maps don't exist in JavaScript. You can use objects, which are similar, but not the same.

hmm well... what do u suggest me... i reallyy have no clue

nvm

Code:

---

var mop = Object();
mop[key] = val;

---

You might want to use the object literals instead. But, if you are just looking for key -> value assignments, you can use associative arrays instead of objects.

Code:

---

var mop = {}; // object
var mop = []; // array

---

thanks for the advice
