2704. To Be Or Not To Be
Description
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 returnstrue
if the two values===
each other. If they are not equal, it should throw an error"Not Equal"
.notToBe(val)
accepts another value and returnstrue
if the two values!==
each other. If they are equal, it should throw an error"Equal"
.
Example 1:
Input: func = () => expect(5).toBe(5) Output: {"value": true} Explanation: 5 === 5 so this expression returns true.
Example 2:
Input: func = () => expect(5).toBe(null) Output: {"error": "Not Equal"} Explanation: 5 !== null so this expression throw the error "Not Equal".
Example 3:
Input: func = () => expect(5).notToBe(null) Output: {"value": true} Explanation: 5 !== null so this expression returns true.
