When you are told to debug the code, if you forget to set the conditional in the if loop to == it will remind you, but it will incorrectly state that it needs to be ===. This might confuse other users.
We have to expect some confusion at this stage. When everything is new, even a little thing can require a larger explanation.
You have me at a loss here, though, since I do not know the lesson to which you refer. Perhaps a link will help get me on the correct bearing. Please post.
Well I was slightly wrong, I'm used to using == to check a conditional, but === works too. I feel like both methods should be shown as they both work but I can see now that the post wasn't wrong, I just didn't realize both methods would work.
You will find that both work in some instances, but not all.
a == b
This is an equality. Consider it in the light of
b being expressions.
Expressions yield a value and the type is determined, thereupon. An equality expression, as the above is also known, does not depend upon the operands yielding the same data type.
1 == '1' => true
console.log(1 === '1'); // false var s = "ONE"; console.log(s === "ONE"); // true
