Defining Read Only Properties in JavaScript | JavaScript Objects Tutorial
By using the Object.defineProperty method you are able to define properties as 'read only' in JavaScript - this is done by setting the 'writable' property to 'true' while defining the property.
In this video I go over how to do this with a simple example of an object literal representing a Person. Using the 'defineProperty' method I define a new property called 'born' which will describe where the Person was born - and since you can't really change where you were born, we will be defining this as a 'read only' property - you can't change it!
