She should change her first name to 'or 1=1;drop table customers;commit;--', sit back, and watch the fireworks. by the way, best use case of this I've ever seen? It was pasted on a sticker on a car's bumper, right below the license plate, in a nice easy to read/OCR font. Now, I've no idea if the speed/traffic/tracking cameras read it and acted on it or not, but the idea amused me.

The value `null` and the value `"null"` are not the same thing in Javascript, and `null == 'null'` is `false`.

  And if we set x=[0], then x==x is true and x!=x is also true... And []+[] = "" And []+{} = [object Object] And {}+[] = 0 And {}+{} = NaN

  If you have already coerced the variable to be a string, then you can end up with with a null value becoming the string "null". E.g. the below statement evaluates to true: new String(null)=="null" And it used to be a lot easier to make that mistake like something with: ""+a Which different browsers handled differently.

Can‘t find the JavaScript connection. Guess you‘re simply trying a little too hard trolling around. Edit: To all the Nulls, thanks for the downvotes.

This was probably SQL. As for JavaScript, I recall how I registered an account with user name "undefined" for TheDailyWTF article comments. Later they moved their comment system and forums to Discourse and due to some bug my account was linked under every item in the list of likes under every post.
