Installation

npm install sum-numbers-fast

Usage

ES Module

import sum from 'sum-numbers-fast';
// or: import { sum } from 'sum-numbers-fast';

console.log(sum(1, 2)); // 3
console.log(sum(1, '2', 3)); // 6
console.log(sum('1.5', 2.5)); // 4

CommonJS

console.log(sum('1.5', 2.5)); // 4

Behavior

• Accepts any number of arguments, numbers, and numeric strings.
• Ignores invalid values (null, undefined, NaN, non-numeric strings, objects, arrays, etc.).
• Throws an Error if no valid numeric values are provided.
• Always returns a Number.

Examples

• sum(1, 2) → 3
• sum(1, "2", 3) → 6
• sum("1.5", 2.5) → 4
