Question

is there a faster way to transform this:

[
    { name: 'name1', value: 'value1' },
    { name: 'name2', value: 'value2' },
    { name: 'name3', value: 'value3' },
    ...
]

into this:

{
    name1: value1,
    name2: value2,
    name3: value3,
    ...
}

without manually looping and filling an object?
could the underscore library have a way to do this? it is already in our application, so
it can be used without an extra cost.

currently i have a manual action,
though i’m not sure it is the best performance i can have.

    var data = [];      // see the array above
    var result = {};
    for(var i = 0; i < data.length; i++)
    {
        var o = data[i];
        result[o.name] = o.value;
    }

Answer 1

I don’t think there is a faster way. With underscore there is a shorter way, but it’s almost certainly slower than your loop:

var result = _.reduce(data, function(r,o) { r[o.name] = o.value; return r; }, {});
