prototypejs - How do I create a Hash from an Array using the Prototype JavaScript framewor? -

i've array ['red', 'green', 'blue']

i want create new hash array, result should be

{'red':true, 'green':true, 'blue':true}

what best way achieve goal using prototype?

just iterate on array , create hash:

var obj  = {}; for(var = 0, l = colors.length; < l; i++) {     obj[colors[i]] = true; } var hash = new hash(obj);

you can create new hash object beginning:

var hash = new hash(); for(var = 0, l = colors.length; < l; i++) {     hash.set(colors[i], true); }

i suggest have @ documentation.
