So, there's about a billion questions here on how to check if an object property in JavaScript is defined or not. They work great. Well, until I have a situation like this:
var obj = {
prop1: {
prop1a: {
prop1aa: "somestring"
}
}
};
//conditional stuff happens, potentially changing obj's structure
//Use your method of choice for checking if this is defined or not:
if (typeof obj.prop2.prop2a.prop2aa !== "undefined") {
//prop2aa is defined, do something with it!
}
However, since prop2 itself isn't defined in some situations, this check throws an error in those situations. Is there a robust way to check if a distant property is defined in an object without resorting to a series of if checks at every single level of the object on the way to the desired property?
