merge two arrays (keys and values) into an object [duplicate]

Answer 1

var r = {},
    i,
    keys = ['one', 'two', 'three'],
    values = ['a', 'b', 'c'];

for (i = 0; i < keys.length; i++) {
    r[keys[i]] = values[i];
}

Answer 2

As long as the two arrays are the same length, you can do this:

var hash = {};
var keys = ['one', 'two', 'three']
var values = ['a', 'b', 'c']

for (var i = 0; i < keys.length; i++)
    hash[keys[i]] = values[i];

console.log(hash['one'])
console.log(hash.two);

Answer 3

keys = ['one', 'two', 'three']
values = ['a', 'b', 'c']

d = {}

for i, index in keys
    d[i] = values[index]

Explanation: In coffeescript you can iterate an array and get each item and its position on the array, or index. So you can then use this index to assign keys and values to a new object.
