numerous items sharing identical key values

I am dealing with an array of objects:

[object, object, object, object, object]

and I need to assign a unique key to each object based on its title:

{test:object, tester:object, foo:object, bar:object, test:object}

This way, instead of accessing the objects using array[0].title, I can simply use array.test. However, if there are multiple objects with the same key, the original one is replaced.

Is it possible to achieve this without adding an index value to the key? If not, would it be better to stick with my original approach of using array[0].title?

Answer №1

Is there a method to assign the same key to multiple objects without overwriting it, apart from adding an index value to the key?

Unfortunately not. Object keys are unique, which means each key can only hold one value. If you need to store multiple values, you can assign an array as the value like { key : [value1, value2 ...]}, but this may not be applicable for your specific issue. The main purpose of objects/maps is to have distinct key-value pairs.

Is my current approach the most efficient way to tackle this problem?

Yes. Utilizing an array data structure to address the problem you described is a good choice.
