Filtering object by keys in lodash

Question

I wrote the function below to return all keys in an object that match a specific pattern. It seems really round-about because there\'s no filter function in lodash for objects,

Answer 1

I don't think you need lodash for this, I would just use Object.keys, filter for matches then reduce back down to an object like this (untested, but should work):

export function keysThatMatch (pattern) {
  return (data) => {
    return Object.keys(data).filter((key) => {
      return key.match(pattern);
    }).reduce((obj, curKey) => {
      obj[curKey] = data[curKey];
      return obj;
    });
  }
}
