Convert Array To Object In Javascript

I'd like to convert an array into an object using one of the properties as key. For instance: var stations = [ { name: 'A Coruna', ds100: 'OECSC' }, ... ]; I'd like to get station

Solution 1:

You could use Object.assign with computed property names.

var stations = [ { name: 'A Coruna', ds100: 'OECSC' }],
    object = stations.reduce((o, a) =>Object.assign(o, { [a.ds100]: a }), {});

console.log(object);
