In this video around 16:00 the instructor says dynamic object property syntax is being used (total[language]). It seems like it’s just regular setting a property on an object using a variable, which here is (destructured from the repo object, the current item being iterated over in the reduce method) language. Did he make a mistake calling it a dynamic object property or am I missing something?
>Solution :
The reason why they called it a dynamic property is because from the perspective of the total object – the language variable that is being passed in as a key can contain any value during the application runtime, hence hypothetically any property can be accessed at different runs – making it dynamic.
So the instructor was correct, even though there is no other official term for using a variable as a property accessor.
