Imagine that we want to apply a series of functions to x if and only if x is non-null: if (x != null) x = a(x) * console.log('New Value is', value) //logs 'New Value is c' * value = getSafe(myObj.a.x,'No Value') //returns 'No Value' * value = getSafe(myObj.a.b,'No Value') //returns c * If property of object exists it is returned, * defaultVal The value returned if the property value does not exist The Cannot read property of undefined TypeError is a descendant of the TypeError object.
