Missing "use strict" even though it's already declared at top of file

Am getting this Missing "use strict" statement even though it's decalred at the top of the file, which confuses me. This error appears twice, for lines 10 and 12.

'user strict';
var elasticsearch = require('elasticsearch');
var client = new elasticsearch.Client({
  host : 'http://localhost:9200'
});
client.search({
  index: 'twitter',
  type: 'tweets'
}).then(function (resp) {
  var hits = resp.hits.hits;
}, function (err) {
  console.trace(err.message);
});

The code above is largely copy and paste from http://www.fullscale.co/elasticjs/

Solution

  • It appears you've made a typo.

    It should be

    'use strict';
