How to assign undefined value in a knockout.js variable?

@scotty_walker 

In Knockout.js, you can assign an undefined value to a variable by simply not initializing the variable with any value. Knockout.js will automatically set the variable to undefined if it is not assigned a value.

For example, in your ViewModel, you can declare a variable without assigning it a value like this:

1

var myVariable;

In the above example, myVariable will be automatically set to undefined. You can then use this variable in your Knockout.js bindings or logic as needed.
