Great video. Can you go further and create a deeper one. I have learn a lot about Wized.

[@fathom5209]

Excellent video. Just the basics but helped sort a couple of questions in my mind. With javascript is seems the more your learn the faster you learn. One question: It seems the === and !== should generally be used, except when assessing null? Maybe != and == is safer with null when the value might be undefined or " " (empty string)?

[@fathom5209]

Further reading suggests checking for an empty string should be handled separately: if (query != null && query !== "") . Does this seem correct?

[@alexiglesias_me]

I always recommend using straight equality checks, and always be explicit about all the types you’re checking for.
If you want to check if something is undefined or an empty string, then I would simply use a negation like:
if (!value) {}
The reason is because undefined, null and an empty string are all falsy values.
