What is appropriate way to generate hash in JavaScript having values as array

Question

I wanted to generate dictionary like below

a = {'A' => [1,2,3], 'B' => [12,13], 'C' => [32,432]} var h = {} gen_h(['A', 1]) gen_h(['A', 2]) gen_h(['B', 13]) gen_h(['C', 32]) gen_h(['C', 432]) 

should give h value as -

h = {'A' => [1,2], 'B' => [13], 'C' => [32,432]} 

Answer 1

This is just normal JavaScript, nothing to do with jQuery.

function gen_h(data){ var key = data[0], // key val = data[1]; // value if(!h[key]){ // does hash exist? h[key] = []; } h[key].push(val); // add value } 

Then you can do:

var h = {}; gen_h(['A', 1]); gen_h(['A', 2]); gen_h(['B', 13]); gen_h(['C', 32]); gen_h(['C', 432]);
