How to use count in dexie.js?

Question

I'm trying to count how many records I have in a table using dexie.js

I try this: alert(db.table.count()); and browser return: [object Dexie.Promise]

If I use console.log(db.table.count()); the console say this:

This table has two records.. I believe that the _value item showing this result, but my problem is that I don't know how I can display this to the user.

I'm a PHP developer and I tried to make a loop and add the results, like this:

var var_quant = 0;
  db.table.orderBy("id").toArray()
  .then(list => {
    list.forEach(item => {
      console.log(`${item.name}`);  
      var_quant = var_quant + 1;
   });
})
.catch(error => { 
// handle error 
});
console.log(var_quant);

And the console displays the names of the bank, but does not add values to the variable var_quant

Any suggestions on how to just get the number of records, in Mysql it was so easy :o.

Most Dexie methods are asynchronous, which (in Javascript) means they'll return Promises. You'll need to use a fulfillment handler or make it synchronous to access the actual number of elements.
