Usage

JavaScript

Here's how to use isnt-number in a JavaScript file:

console.log(!isNotNumber(123)); // true, like isNumber >.<
console.log(isNotNumber(NaN)); // true

console.log(isEmojiNotNumber("A")); // true
console.log(isEmojiNotNumber("①")); // false
console.log(isEmojiNotNumber("1️⃣")); // false

console.log(isNotNumberEmoji("hello")); // `🙂` 
console.log(isNotNumberEmoji(1)); //  `🙁`
