Difference between .exec() and .execPopulate() in Mongoose?

Here I answer what is the difference between .exec() and .execPopulate() in Mongoose? .exec() is used with a query while .execPopulate() is used with a document Syntax for .exec() is as follows: Model.query() . populate ( 'field' ) . exec () // returns promise . then ( function ( document ) { console . log ( document ); }); Syntax for .execPopulate() is as follows: fetchedDocument . populate ( 'field' ) . execPopulate () // returns promise . then ( function ( document ) { console . log ( document ); }); When working with individual document use .execPopulate(), for model query use .exec(). Both returns a promise. One can do without .exec() or .execPopulate() but then has to pass a callback in populate.

Resolve: Uncaught TypeError: firebase.database is not a function

If you are getting the error: Uncaught TypeError: firebase.database is not a function Resolve it by including firebase-database.js in your html page as follows: <!-- The core Firebase JS SDK is always required and must be listed first --> <script defer src = "https://www.gstatic.com/firebasejs/6.2.4/firebase-app.js" ></script> <script defer src = "https://www.gstatic.com/firebasejs/3.1.0/firebase-database.js" ></script> That is it.
