DataviewJS - How can I make a Dictionary?

[Another5405]

Hi again,
I want to make a Dictionary to record file number like Dictionary<string,int> in C#
according my experience , can not in decare value in DataviewJS
(like:
var persons: { [id: string] : IPerson; } = {};
let A : int = 3
)

In my thought,I will use for loop to sorting array, and return the number of file if match.
but this funtion will cost so much calculate(calculate<file.count*file.count)

How can I improve the Dictionary type?Thank You.

I'm not sure you can declare types like this in JS.

I use Array.indexOf for now.

The equivalent to the C# Dictionary is just a javascript object:

let dict = {};
dict[key] = value;

JavaScript does not support typing (that is only TypeScript, which DataviewJS does not support).
