Knockout.js pulling element from observableArray returns undefined

Question

Here is the code I am using in a larger function:

this.categoriesToSearch = ko.observableArray(["Food"]);// Initial selection
console.log(this.categoriesToSearch[0]);

Running this returns undefined. Knockout.js documentation says observableArrays are supposed to be read that way. Is there a better way to read observableArrays?

Answering my own question since I came up with the answer right after posting: observableArrays are functions so the correct way to pull an item is:

this.categoriesToSearch()[0]

Try this.categoriesToSearch()[0]

KO documentation says you have to handle observable array like a function call.
