Instructions

In this challenge, you must verify the equality of two different values given the parameters a and b.

Both the value and type of the parameters need to be equal. The possible types of the given parameters are:

• Numbers
• Strings
• Booleans (false or true)
• Special values: undefined, null and NaN

What have you learned so far that will permit you to do two different checks (value and type) with a single statement?

Implement a function that returns true if the parameters are equal, and `false`` if they are not.

Examples

checkEquality(1, true) // false
// A number and a boolean: the value and type are different.checkEquality(0, "0") // false
// A number and a string: the type is different.checkEquality(1,  1) // true
// A number and a number: the type and value are equal.

Notes

• N/A

Solutions

function checkEquality(a, b) {return a === b ;
}

TestCases

let Test = (function(){return {assertEquals:function(actual,expected){if(actual !== expected){let errorMsg = `actual is ${actual},${expected} is expected`;throw new Error(errorMsg);}}}
})();Test.assertEquals(checkEquality(1, true), false, "Example #1")
Test.assertEquals(checkEquality(0, "0"), false, "Example #2")
Test.assertEquals(checkEquality(1, 1), true, "Example #3")
Test.assertEquals(checkEquality(0, ""), false)
Test.assertEquals(checkEquality(1, "1"), false)
Test.assertEquals(checkEquality(0, false), false)
Test.assertEquals(checkEquality(NaN, NaN), false)
Test.assertEquals(checkEquality(null, undefined), false)
Test.assertEquals(checkEquality(undefined, undefined), true)
Test.assertEquals(checkEquality(false, null), false)
