A simple function that returns true if the input is not a number
npm install isnt-numberA npm package that gives you a function that returns true if the input is not a number.
It's a new approach for everyone who thinks differently!
You can install the package via npm:
``bash`
npm install isnt-number
Here's how to use isnt-number in a JavaScript file:
`javascript
const { isNotNumber, isEmojiNotNumber, isNotNumberEmoji } = require("isnt-number");
console.log(isNotNumber("hello")); // true
console.log(isNotNumber(123)); // false
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)); //
To use isnt-number in a TypeScript file, follow these steps:
1. Install the package:
`bash`
npm install isnt-number
2. Install the type definitions:
`bash`
npm install --save-dev @types/isnt-number
3. Use the functions in your TypeScript code:
`javascript
import { isNotNumber, isEmojiNotNumber, isNotNumberEmoji} from "isnt-number";
console.log(isNotNumber("hello")); // true
console.log(isNotNumber(123)); // false
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)); //
- value: The value to check.
- Returns: true if the value is not a number, otherwise false.
- value: The value to check.
- Returns: true if the value is not a number emoji, otherwise false.
- value: The value to check.
- Returns: 🙂 if the value is not a number, otherwise 🙁.
The isEmojiNotNumber function checks for the following types of number emojis:
- Circled numbers (1-20): ① ② ③ etc.
- Negative circled numbers (1-20): ⓿ ❶ ❷ etc.
- Filled circled numbers (1-10): ➀ ➁ ➂ etc.
- Keycap numbers (0-9): 0️⃣ 1️⃣ 2️⃣ etc.
Any character that is not one of these number emojis will return true`.
