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

Question

Is there a common Javascript/Coffeescript-specific idiom I can use to accomplish this? Mainly out of curiosity.

I have two arrays, one consisting of the desired keys and the other one consisting of the desired values, and I want to merge this in to an object.

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

Answer 1

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

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

console.log(r);

.as-console-wrapper { max-height: 100% !important; top: 0; }
