Understanding NaN in JavaScript: Representation and Comparison

JavaScript’s NaN represents undefined numeric results, appears when operations like Math.sqrt(-1) occur, has multiple binary forms, and is distinguished as Quiet or Signaling; because NaN !== NaN, comparisons rely on special checks such as isnan, with implementations varying across environments like V8 and Apple’s C library.
