Undefined Is Not Null: There Is a Difference – JavaScript Developer Humor
undefined !== null // there is a difference. Every JavaScript developer has been bitten by this one: two values that look like “nothing” but aren’t the same thing, and a strict equality operator that knows it. This design shows the comparison as a block of code in terminal green and red, with the punchline written as a code comment.
Made for web developers, frontend engineers and anyone who has ever debugged a “cannot read properties of undefined” error at 2 a.m. A good fit for code review survivors, team chats and coworker gift swaps.
