lucono Fixing the JavaScript and ES6 NaN problem The NaN value problem In JavaScript: typeof 5 === ’number’; typeof NaN === ’number’; // Also! The classification of the JavaScript NaN value as the number type is rarely ever useful in JavaScript applications, and usually only creates many additional instances in an application where it becomes necessary to perform additional type and data checks that could have been avoided in the number context. From MDN : It is rather rare to use NaN in a program. It is the returned value when Math functions fail (Math.sqrt(-1)) or when a function trying to parse a number fails (parseInt("blabla")) . A different approach A different approach is to have the NaN value completely decoupled and distinct from the number type, effectively eliminating the need for applications to explicitly handle NaN values whenever expecting number types. NaN values are particularly problematic in JavaScript applications because though they are reported as the number type
