我如何在打字稿中使用字典查询linq？

Question

There is interface of dictionary:

interface Dictionary<T> {
    [Key: string]: T;
}

And some class that counts daily repeating of some exersizes:

export class ClassName {
   DailyReapeatCount: Dictionary<number> = {};
}

Let's initialize it:

let myClass = new ClassName();
        myClass.DailyReapeatCount['exersize_01'] = 3;
        myClass.DailyReapeatCount['exersize_02'] = 4;
        // ... and so on

Then I need to check if it has any exersize with DailyReapeatCount more then 5:

// pseudo code there
let isAnyExist = myClass.DailyReapeatCount.some(p => p.value > 5);

There I get ts notification:

Cannot invoke an expression whose type lacks a call signature. Type Number has no compatible call signatures."

How do I get this query?

Use standard Map (it's the same as Dictionary in C#):

const dictionary = new Map<string, number>([
  ["one", 1], 
  ["two", 2],
  ["five", 5],
]);

const values = Array.from(dictionary.values());
const isExist = values.some(v => v < 5);
console.log(isExist);

// In addition you can do dictionary-based things like:
console.log(dictionary.has("five")); // check is key exists
