Javascript arrays and Meteor session

Question

I have made an interesting observation. When trying to update an array that is stored in the Meteor session storage, the following code will not propagate the changes:

Answer 1

In short: Use var index = cardTags.indexOf(this.toString()); instead.

Long version:

When using strings in JavaScript, those are strings, whereas typeof 'test' returns string.

Let's take a look at the following code in order to get find out another way to represent strings in JavaScript:

var func = function () {
    return this;
};
console.log(func.call('test'));

The console (at least FireBug) won't show us "test", but instead it shows String {0="t", 1="e", 2="s", 3="t" }. typeof would return "object".

The content of the this statement seems to need to be an object. In order to convert a string into a "String" object we can do console.log(new String('test'));, which is the same as the previously logged value.

To convert a string object into a string (data type), just use its prototype toString.
