let json_doc = {
    'ensembl': {
        'gene': 1017
    }
};
let template = {'ensembl': 'ensembl.gene'};
transform(json_doc, template); // returns {'ensembl': 1017}

Nested Template

let json_doc = {
    'ensembl': {
        'gene': 1017
    },
    'wikipathway': [
        {
            'id': 'WP123',
            'name': 'aaa'
        },
        {

        'id': 'wikipathway.id',
        'name': 'wikipathway.name'
    }
};
let res = transform(json_doc, template); //returns {'ensembl': 1017, 'pathway': [{'id': 'WP123', 'name': 'aaa'}, {'id': 'WP1234', 'name': 'aaaa'}]}
