JavaScript Equality Bedtime Horror

Description

The image is a three-panel cartoon of a man reading a large blue book with a yellow "JS" logo on the cover. In the middle panel, the page reads "Type coercion:" followed by the expression "[null,null] == \"\"" and the result "true," while the reader points at the line. The final panel shows his unsettled reaction, with a small "t.me/dev_meme" watermark at the bottom left. The joke targets JavaScript's loose equality rules, where arrays stringify during comparison and dynamic coercion produces results that look absurd unless you know the specification path.
