You can categorize the objects of your array by one of its keys in the following way:

function mapByField(collection, fieldName){

    var collectionIdx = collection.length || 0;
    var result = {};

    while(collectionIdx--){
        var obj = collection[collectionIdx];

        if(!result[obj[fieldName]]){
            result[obj[fieldName]] = [];
        }

        result[obj[fieldName]].push(obj);
    }

    return result;
}

Usage:

var data = [
    {id: 1, proveedor:'prov1', precio: 1},
    {id: 2, proveedor:'prov1', precio: 24},
    {id: 3, proveedor:'prov2', precio: 54},
    {id: 4, proveedor:'prov2', precio: 7},
    {id: 5, proveedor:'prov2', precio: 87},
    {id: 6, proveedor:'prov3', precio: 24},
    {id: 7, proveedor:'prov4', precio: 23},
    {id: 8, proveedor:'prov4', precio: 89}
];

var res = mapByField(data, 'proveedor');

Result:

{
    prov1: [...], //ids: 1,2
    prov2: [...], //ids: 3,4,5
    prov3: [...], //ids: 6
    prov4: [...], //ids: 7,8
}
