chetan-js-polyfills

A lightweight JavaScript polyfill library to bring modern JS features to older environments. Simple, modular, and dependency-free.

🎯 Focused on minimalism — only polyfills you actually need.

🚀 Features

• ✅ Polyfills for modern JavaScript methods (ES6+)
• ✅ Zero dependencies
• ✅ Works in old browsers (like IE11+)
• ✅ Tiny bundle size

📦 Installation

Install via npm:

npm install chetan-js-polyfills

Or using Yarn:

yarn add chetan-js-polyfills

🛠️ Usage

Automatic Polyfills (Prototype Methods)

When you import the package, these polyfills are added to the respective prototypes:

• Function.prototype:
  • myCall, myBind, myApply
• Array.prototype:
  • myMap, myFilter, myReduce, mySlice, myFlat
• Object:
  • myCreate

import 'chetan-js-polyfills';
// Now you can use the polyfilled methods directly on Function, Array, and Object

Named Utility Exports

You can also import utility functions as named exports:

• myDeepCloneObject
• myCurrySum
• myDeepCompareObjects
• myAbstractEquality
• myDebounce
• myThrottleBasicUsingDate
• myThrottleBasicUsingTimer
• myThrottleAdvance
• myNew
• mySetTimeout
• myClearTimeout

import {
  myDeepCloneObject,
  myCurrySum,
  myDeepCompareObjects,
  myAbstractEquality,
  myDebounce,
  myThrottleBasicUsingDate,
  myThrottleBasicUsingTimer,
  myThrottleAdvance,
  myNew,
  mySetTimeout,
  myClearTimeout
} from 'chetan-js-polyfills';

This approach keeps your bundle size small and lets you use only what you need.
