variable as index in an associative array - Javascript

Question

I\'m trying to create an associative array, create an empty array, and then add a (indexName -> value) pair:

var arrayName = new Array;

arrayName[\         


        

Answer 1

Indeed, there was no need for an array object, a simple object did the job; further more an array introduced the need to use quotes inside the square brackets obj["var1 + var2"] to access the object property's value and not the value associated with an index (i think); the quotes transformed "var1 + var2" into a string. Using a simple object eliminated the need for quotes, so I can use obj[var1 + var2], wich worked :)

Thanks everyone !
