/**
 * Creates an object that maps the result of `valueExtractor` with a key
 * resulting from running `keyExtractor` on each item in `data`. Duplicate keys
 * are overwritten, guaranteeing that the extractor functions are run on each
 * item in `data`.
 *
 * There are several other functions that could be used to build an object from
 * an array:
 * * `fromKeys` - Builds an object from an array of *keys* and a mapper for values.
 * * `indexBy` - Builds an object from an array of *values* and a mapper for keys.
 * * `fromEntries` - Builds an object from an array of key-value pairs.
 * Refer to the docs for more details.
 *
 * @param data - The items used to pull/extract the keys and values from.
 * @param keyExtractor - Computes the key for item.
 * @param valueExtractor - Computes the value for the item.
 * @signature
 *   R.pullObject(data, keyExtractor, valueExtractor);
 * @example
 *   R.pullObject(
 *     [
 *       { name: "john", email: "john@remedajs.com" },
 *       { name: "jane", email: "jane@remedajs.com" }
 *     ],
 *     R.prop("name"),
 *     R.prop("email"),
 *   ); // => { john: "john@remedajs.com", jane: "jane@remedajs.com" }
