// LeetCode problem

// Write a function expect that helps developers test their code.
// It should take in any value val and return an object with the following two functions.

// toBe(val) accepts another value and returns true if the two values === each other.
// If they are not equal, it should throw an error "Not Equal".

// notToBe(val) accepts another value and returns true if the two values !== each other.
// If they are equal, it should throw an error "Equal".

const expect = function(val) {
    return {
        toBe: (v) => {
            if(v === val) return true
            else throw new Error("Not Equal");
        },
        notToBe: (v) => {
            if(v !== val) return true
            else throw new Error("Equal");
        }
    }
}
