Comparison with the Strict Equality Operator - Difference between "==" and "===" wording

Challenge Comparison with the Strict Equality Operator has an issue. User Agent is: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/57.0.2987.133 Safari/537.36. Please describe how to reproduce this issue, and include links to screenshots if possible.

My code:

// Setup
function testStrict(val) {
  if (val) { // Change this line
    return "Equal";
  }
  return "Not Equal";
}

// Change this value to test
testStrict(10);

The explanation for the difference between “==” and “===” is incorrect. They both test for the data type of the compared elements, but “===” does not allow the elements to be converted to other data types if they are not the same, where as “==” (a.k.a. coercion), does allow the elements to be converted.

I agree with @dhcodes, however, I think there should be another module added for users to implement with the equality operator (==) and the strict equality operator (===) in the same module to hit home the difference. I think that would be a good place for @dhcodes example. Right now you learn and practice with them separately and it would be good to have a module that you are required to use both to make sure you understand the difference between them.

These links may also be helpful to include for the new said module. They are directly from the Ecmascript Specification website: == Equality Algorithm ( http://www.ecma-international.org/ecma-262/5.1/#sec-11.9.3 ) === Strict Equality Algorithm ( http://www.ecma-international.org/ecma-262/5.1/#sec-11.9.6 )

@dakshshah96 I think your description is sufficient. The only update I think I may make is to say ‘data type’ instead of ‘type’ to match the wording used in the modules.

I think in addition to what @dakshshah96’s suggestion, what really helps with this concept are examples. Something like:

typeof 3 // return 'number'
typeof '3' // returns 'string'

3 == '3' // returns true because Javascript is doing a type conversion on the string
3 === '3' // returns false because strict equality does not allow the type conversion and as demonstrated in the first two lines of code, 3 is a type of 'number' but '3' is a type of 'string'
