logChange is an example of an extension, not part of the standard library. To add extensions, simply extend the interface outside of the definition file:
interface KnockoutExtenders {
logChange(target: KnockoutObservableAny, option: string): KnockoutObservableAny;
}
Although this function is available via knockout-{version}.debug.js, it is
not part of the minified knockout-{version}.js file. Invoking this function
will cause a runtime javascript error when invoked against the minified js.
