Answer 1

Let's say you have the following JavaScript array:

var list = [
    {
         name: "sEcho",
         value: 1
    },
    {
         name: "iColumns",
         value: 12
    },
    ...
];

You can convert it into the format you want as follows:

var table = _.reduce(list, function (table, item) {
    table[item.name] = item.value;
    return table;
}, {});

It's not a one liner, but I don't think you literally meant a one liner. Did you?

Here's a one liner if you really meant a one liner:

var t = _.reduce(list, function (t, i) { return t[i.name] = i.value, t; }, {});

Yes, others have provided the same answer. However that's only because the answer to your question is so simple.
