I have some ES6 code where I am passing in some named parameters of a defined options object like so...
configureMapManager({ mapLocation, configuredWithDataCallback, locationHasChanged })
{
if (mapLocation) console.log(mapLocation)
}
This is a contrived case and the following calls will work fine...
configureMapManager({ mapLocation: "BS1 3TQ" })
configureMapManager({})
But this will blow up...
configureMapManager()
...because I cant check that the passed in object is defined (It's not because I called the method without any parameters). How can I do this without having to rewrite this like this (which sucks because then you lose visibility of the allowed parameters within the object)...
configureMapManager(options)
{
if (options && options.mapLocation) console.log(mapLocation)
}
