Simple typescript function

It has been several hours since I have been trying to create a simple function that I know is possible to create, because I once somehow managed to do that, but not now. I just want to create a function that takes other functions. ...callbacks Each of those functions will be called inside, and a single value will be passed (context). Context: It is an object that takes the result of the previous callback. execution. so like [0]: number, [1]: {a: number} The problem is that I cannot have a type of those results, but instead it displays as [x:string]:any. Again once i somehow implemented it and now i just cant. Thank you for any help

Zustand question

const useStore = create((set) => ({
  count: 0,
  increment: () => set((state) => ({ count: state.count + 1 })),
  decrement: () => set((state) => ({ count: state.count - 1 })),
}));

const useStore = create((set) => ({
  count: 0,
  increment: () => set((state) => ({ count: state.count + 1 })),
  decrement: () => set((state) => ({ count: state.count - 1 })),
}));

i know that we should get count by useStore((state)=>state.count) right? But what about increment and decrement function, cant i just use useStore.getState.increment? It is not like the inrement function re-render is needed for reactivity, there is nothing that depends on it?

Genius ask the Java problem question in Typescript relate server

I currently learning JAVA, so i rewriting my old JS algorithm from leetcode to practice JAVA. the problem is this code right below make "Time Limit Exceeded" error.

class Solution {
    public int mySqrt(int x) {
        long left = 0;
        long right = x;
        while(left <= right){
            long mid = left + (right - left) / 2;
            long doub = mid * mid;
            if(doub == x){
                return (int) mid;
            }
            if(doub > x){
                left =  mid - 1;
            }
            if(doub < x){
                right = mid + 1;
            }
        }
        return (int) right;
    }
}

class Solution {
    public int mySqrt(int x) {
        long left = 0;
        long right = x;
        while(left <= right){
            long mid = left + (right - left) / 2;
            long doub = mid * mid;
            if(doub == x){
                return (int) mid;
            }
            if(doub > x){
                left =  mid - 1;
            }
            if(doub < x){
                right = mid + 1;
            }
        }
        return (int) right;
    }
}

but when you use same code but update else if else instead of just if guards it works fine.

class Solution {
    public int mySqrt(int x) {
        long left = 0;
        long right = x;

        while (left <= right) {
            long mid = left + (right - left) / 2;
            long doub = mid * mid;

            if (doub == x) {
                return (int) mid;
            } else if (doub > x) {
                right = mid - 1;
            } else {
                left = mid + 1;
            }
        }
        return (int) right;
    }
}

class Solution {
    public int mySqrt(int x) {
        long left = 0;
        long right = x;

        while (left <= right) {
            long mid = left + (right - left) / 2;
            long doub = mid * mid;

            if (doub == x) {
                return (int) mid;
            } else if (doub > x) {
                right = mid - 1;
            } else {
                left = mid + 1;
            }
        }
        return (int) right;
    }
}

i really can not understand why, because i tried to add "continue" at the end of every if statement and the same error occur when is should skip in that logic cicle. Thanks in advance
