Create specific format string from array - jquery -

its simple question

i have 1 jquery arrary

arry = [ 'apple=1', 'apple=2', 'orange=5', 'orange=7', 'orange=9', 'guava=12', 'guava=11' ];  

i want convert above array string

str = 'apple=1*2*~orange=5*7*9~guava=12*11'; 

kindly me in this...

(actually looking various interesting ways this)

there more straightforward ways, if know you're going exact output, find useful first rearrange array in proper dictionary:

var dict = {}; arry.foreach(function(item) {    var parts = item.split('=');    var key = parts[0];    var value = parts[1];     if(key in dict) {       dict[key].push(value);    } else {       dict[key] = [value];    } }); 

... , concatenate string that:

object.keys(dict).map(function(key) {    return [key, '=', dict[key].join('*')].join(''); }).join('~');
