/**
 * <p> ☁️ Returns the latest value and metadata associated with an entry, or a specific version if versionId is provided. </p>
 * API Key Permissions:
 * <ul>
 *  <li> Read entries </li>
 *  <li> Read version </li>
 * </ul>
 * @category Datastores
 * @param {number} universeId - The ID of the universe
 * @param {string} datastoreName - Name of the data store
 * @param {string} entryKey - The key which identifies the entry.
 * @param {string=} [scope=global] - Defaults to global, similar to Lua API.
 * @param {string=} versionId - The version to inspect
 * @returns {Promise<DatastoreEntry>}
 * @example const noblox = require("noblox.js")
 * const entry = await noblox.getDatastoreEntry({ universeId: 127407415, datastoreName: 'LevelStore', entryKey: 'Level_User' })
