How to use the wikidata-sdk.getEntities function in wikidata-sdk

const parseWikidata = function (data) {
  const list = Array.isArray(data) ? data : data.trim().split(/(?:[\s,]\s*)/g)
  return [].concat(wdk.getEntities(list, ['en']))
}

const fetchWikidataLabel = function (q, lang) {
  const ids = Array.isArray(q) ? q : typeof q === 'string' ? q.split('|') : ''
  const url = wdk.getEntities(ids, [lang], 'labels')
  const entities = JSON.parse(fetchFile(url)).entities || {}

  return Object.keys(entities).map(entityKey => (entities[entityKey].labels[lang] || {}).value)
}

const fetchWikidataLabelAsync = async function (q, lang) {
  const ids = Array.isArray(q) ? q : typeof q === 'string' ? q.split('|') : ''
  const url = wdk.getEntities(ids, [lang], 'labels')
  const entities = JSON.parse(await fetchFileAsync(url)).entities || {}

  return Object.keys(entities).map(entityKey => (entities[entityKey].labels[lang] || {}).value)
}
